Constantine and the New Testament

Chances are good that you know there were other gospels—accounts of the life and teachings of Jesus—that never made it into the Bible. That fact has become part of the pop culture knowledge base since the explosion of Dan Brown’s bestselling novel, The DaVinci Code.

Constantine and the New Testament - To Choose or Not To Choose?

That raises the question of why books like the Gospel of Mary, the Gospel of Judas, the Gospel of Thomas, and other ancient books (like 1 Enoch) never made it into the Bible. One conspiracy theory is that the books of the New Testament were picked by Emperor Constantine at the Council of Nicea. The new emperor was friendly toward Christianity (his mother was a Christian and he later converted, though some dispute his authenticity). Constantine presided over the conference (at least the day he was there), so did he lay down the imperial law and tell the assembled bishops what books belonged in the New Testament?

Constantine and the New Testament: The Council of Nicea

To evaluate this claim it’s a good idea to start with the council of Nicea itself. The council met in ancient Nicea (now İznik, Turkey), in 325 A.D. It was the first ecumenical council in the history of Christianity (i.e., a council representing the entirety of Christendom). The council was indeed called by the emperor.

Constantine’s major concern was division in the church across his empire. There were a lot of disagreements. Documentary evidence from the early centuries of the church tell us that there was a lot of discussion about which books should be considered sacred alongside the sacred books of the Old Testament (the Hebrew Bible of Judaism), but there was no broad consensus. More famous disagreements included issues like the date of Easter, what to do with lapsed clergy, and clergy ethics.

The conference is not known for any decision about the New Testament. Rather, it became famous for its decision about Arianism, the teaching of Arius of Alexandria. Arius taught that Jesus was not eternal and pre-existent but a created being (“there was a time when the Son was not”). This meant that Arius denied there was a Trinity. The council rejected Arianism and produced the Nicene Creed in response.

Constantine and the New Testament: The Decisions of Nicea

We know for sure that Constantine did notchoose the books of the New Testament for the bishops at this conference for a simple reason: the decisions of the conference were recorded and we have them. They are referred to historically as the “canons” of the Council of Nicea. There were twenty of them. Most can be easily understood, but some require context or explanation of vocabulary (see CHE). Here are the decisions:

Canon 1

If anyone in sickness has been subjected by physicians to a surgical operation, or if he has been castrated by barbarians, let him remain among the clergy; but, if any one in sound health has castrated himself, it behooves that such an one, if [already] enrolled among the clergy, should cease [from his ministry], and that from henceforth no such person should be promoted. But, as it is evident that this is said of those who willfully do the thing and presume to castrate themselves, so if any have been made eunuchs by barbarians, or by their masters, and should otherwise be found worthy, such men the Canon admits to the clergy.

Canon 2

Forasmuch as, either from necessity, or through the urgency of individuals, many things have been done contrary to the Ecclesiastical canon, so that men just converted from heathenism to the faith, and who have been instructed but a little while, are straightway brought to the spiritual laver, and as soon as they have been baptized, are advanced to the episcopate or the presbyterate, it has seemed right to us that for the time to come no such thing shall be done. For to the catechumen himself there is need of time and of a longer trial after baptism. For the apostolic saying is clear, Not a novice; lest, being lifted up with pride, he fall into condemnation and the snare of the devil. But if, as time goes on, any sensual sin should be found out about the person, and he should be convicted by two or three witnesses, let him cease from the clerical office. And whoever shall transgress these [enactments] will imperil his own clerical position, as a person who presumes to disobey the great Synod.

Canon 3

The great Synod has stringently forbidden any bishop, presbyter, deacon, or any one of the clergy whatever, to have a subintroducta dwelling with him, except only a mother, or sister, or aunt, or such persons only as are beyond all suspicion. (Note: a subintroductawas a female virgin; e.g., a maid or servant girl)

Canon 4

It is by all means proper that a bishop should be appointed by all the bishops in the province; but should this be difficult, either on account of urgent necessity or because of distance, three at least should meet together, and the suffrages of the absent [bishops] also being given and communicated in writing, then the ordination should take place. But in every province the ratification of what is done should be left to the Metropolitan.

Canon 5

Concerning those, whether of the clergy or of the laity, who have been excommunicated in the several provinces, let the provision of the canon be observed by the bishops which provides that persons cast out by some be not readmitted by others. Nevertheless, inquiry should be made whether they have been excommunicated through captiousness, or contentiousness, or any such like ungracious disposition in the bishop. And, that this matter may have due investigation, it is decreed that in every province synods shall be held twice a year, in order that when all the bishops of the province are assembled together, such questions may by them be thoroughly examined, that so those who have confessedly offended against their bishop, may be seen by all to be for just cause excommunicated, until it shall seem fit to a general meeting of the bishops to pronounce a milder sentence upon them. And let these synods be held, the one before Lent, (that the pure Gift may be offered to God after all bitterness has been put away), and let the second be held about autumn.

Canon 6

Let the ancient customs in Egypt, Libya and Pentapolis prevail, that the Bishop of Alexandria have jurisdiction in all these, since the like is customary for the Bishop of Rome also. Likewise in Antioch and the other provinces, let the Churches retain their privileges. And this is to be universally understood, that if anyone be made bishop without the consent of the Metropolitan, the great Synod has declared that such a man ought not to be a bishop. If, however, two or three bishops shall from natural love of contradiction, oppose the common suffrage of the rest, it being reasonable and in accordance with the ecclesiastical law, then let the choice of the majority prevail.

Canon 7

Since custom and ancient tradition have prevailed that the Bishop of Ælia [i.e., Jerusalem] should be honoured, let him, saving its due dignity to the Metropolis, have the next place of honour.

Canon 8 (Note: the Cathari mentioned herein are not the medieval Cathari persecuted by the Church)

Concerning those who call themselves Cathari, if they come over to the Catholic and Apostolic Church, the great and holy Synod decrees that they who are ordained shall continue as they are in the clergy. But it is before all things necessary that they should profess in writing that they will observe and follow the dogmas of the Catholic and Apostolic Church; in particular that they will communicate with persons who have been twice married, and with those who having lapsed in persecution have had a period [of penance] laid upon them, and a time [of restoration] fixed so that in all things they will follow the dogmas of the Catholic Church. Wheresoever, then, whether in villages or in cities, all of the ordained are found to be of these only, let them remain in the clergy, and in the same rank in which they are found. But if they come over where there is a bishop or presbyter of the Catholic Church, it is manifest that the Bishop of the Church must have the bishop's dignity; and he who was named bishop by those who are called Cathari shall have the rank of presbyter, unless it shall seem fit to the Bishop to admit him to partake in the honour of the title. Or, if this should not be satisfactory, then shall the bishop provide for him a place as Chorepiscopus, or presbyter, in order that he may be evidently seen to be of the clergy, and that there may not be two bishops in the city.

Canon 9

If any presbyters have been advanced without examination, or if upon examination they have made confession of crime, and men acting in violation of the canon have laid hands upon them, notwithstanding their confession, such the canon does not admit; for the Catholic Church requires that [only] which is blameless.

Canon 10

If any who have lapsed have been ordained through the ignorance, or even with the previous knowledge of the ordainers, this shall not prejudice the canon of the Church; for when they are discovered they shall be deposed.

Canon 11

Concerning those who have fallen without compulsion, without the spoiling of their property, without danger or the like, as happened during the tyranny of Licinius, the Synod declares that, though they have deserved no clemency, they shall be dealt with mercifully. As many as were communicants, if they heartily repent, shall pass three years among the hearers; for seven years they shall be prostrators; and for two years they shall communicate with the people in prayers, but without oblation.

Canon 12

As many as were called by grace, and displayed the first zeal, having cast aside their military girdles, but afterwards returned, like dogs, to their own vomit, (so that some spent money and by means of gifts regained their military stations); let these, after they have passed the space of three years as hearers, be for ten years prostrators. But in all these cases it is necessary to examine well into their purpose and what their repentance appears to be like. For as many as give evidence of their conversions by deeds, and not pretence, with fear, and tears, and perseverance, and good works, when they have fulfilled their appointed time as hearers, may properly communicate in prayers; and after that the bishop may determine yet more favourably concerning them. But those who take [the matter] with indifference, and who think the form of [not] entering the Church is sufficient for their conversion, must fulfil the whole time.

Canon 13

Concerning the departing, the ancient canonical law is still to be maintained, to wit, that, if any man be at the point of death, he must not be deprived of the last and most indispensable Viaticum. But, if any one should be restored to health again who has received the communion when his life was despaired of, let him remain among those who communicate in prayers only. But in general, and in the case of any dying person whatsoever asking to receive the Eucharist, let the Bishop, after examination made, give it him.

Canon 14

Concerning catechumens who have lapsed, the holy and great Synod has decreed that, after they have passed three years only as hearers, they shall pray with the catechumens.

Canon 15

On account of the great disturbance and discords that occur, it is decreed that the custom prevailing in certain places contrary to the Canon, must wholly be done away; so that neither bishop, presbyter, nor deacon shall pass from city to city. And if any one, after this decree of the holy and great Synod, shall attempt any such thing, or continue in any such course, his proceedings shall be utterly void, and he shall be restored to the Church for which he was ordained bishop or presbyter.

Canon 16

Neither presbyters, nor deacons, nor any others enrolled among the clergy, who, not having the fear of God before their eyes, nor regarding the ecclesiastical Canon, shall recklessly remove from their own church, ought by any means to be received by another church; but every constraint should be applied to restore them to their own parishes; and, if they will not go, they must be excommunicated. And if anyone shall dare surreptitiously to carry off and in his own Church ordain a man belonging to another, without the consent of his own proper bishop, from whom although he was enrolled in the clergy list he has seceded, let the ordination be void.

Canon 17

Forasmuch as many enrolled among the Clergy, following covetousness and lust of gain, have forgotten the divine Scripture, which says, He has not given his money upon usury, and in lending money ask the hundredth of the sum [as monthly interest], the holy and great Synod thinks it just that if after this decree any one be found to receive usury, whether he accomplish it by secret transaction or otherwise, as by demanding the whole and one half, or by using any other contrivance whatever for filthy lucre's sake, he shall be deposed from the clergy and his name stricken from the list.

Canon 18

It has come to the knowledge of the holy and great Synod that, in some districts and cities, the deacons administer the Eucharist to the presbyters, whereas neither canon nor custom permits that they who have no right to offer should give the Body of Christ to them that do offer. And this also has been made known, that certain deacons now touch the Eucharist even before the bishops. Let all such practices be utterly done away, and let the deacons remain within their own bounds, knowing that they are the ministers of the bishop and the inferiors of the presbyters. Let them receive the Eucharist according to their order, after the presbyters, and let either the bishop or the presbyter administer to them. Furthermore, let not the deacons sit among the presbyters, for that is contrary to canon and order. And if, after this decree, any one shall refuse to obey, let him be deposed from the diaconate.

Canon 19

Concerning the Paulianists who have flown for refuge to the Catholic Church, it has been decreed that they must by all means be rebaptized; and if any of them who in past time have been numbered among their clergy should be found blameless and without reproach, let them be rebaptized and ordained by the Bishop of the Catholic Church; but if the examination should discover them to be unfit, they ought to be deposed. Likewise in the case of their deaconesses, and generally in the case of those who have been enrolled among their clergy, let the same form be observed. And we mean by deaconesses such as have assumed the habit, but who, since they have no imposition of hands, are to be numbered only among the laity.

Canon 20

Forasmuch as there are certain persons who kneel on the Lord's Day and in the days of Pentecost, therefore, to the intent that all things may be uniformly observed everywhere (in every parish), it seems good to the holy Synod that prayer be made to God standing.

Constantine and the New Testament: The Books of the New Testament

If Constantine didn’t dictate what books were in the New Testament, how did we wind up with those books and not others? We know a lot about this as well. It’s not what Dan Brown told his readers.

Briefly, by 100 A.D. all the books that are in the New Testament today were written. When it comes to the gospels, an ancient document called the Diatessaron (by Tatian) produced ca. 160-175 A.D. is especially important. The Diatessaron was a harmony of the four gospels we now have in the New Testament. Tatian knew of other gospels (like the Gospel of Thomas) but did not include them in his harmony. This tells us clearly they had lesser status long before Nicea.

Early lists of sacred books to Christians have survived. The Muratorian Fragment listed all the current New Testament books except for Hebrews, 1-2 Peter, and 3 John. The writer mentioned some books that had been rejected. By 200 A.D. all the normative, accepted New Testament books are quoted or alluded to in writings of important church fathers like Tertullian, Irenaeus, and Clement of Alexandria. Clement’s writing included notes about several other books that had not gained acceptance.

The historian Eusebius (b. 260/265 – d. 339/340 A.D.) kept records of the discussions about various books. He made several different lists which are important for our question. Specifically Eusebius made lists of undisputed books, books approved by many in the church, books considered spurious (they had orthodox content but no apostolic authority), and books there were to be rejected. The following excerpt is representative of the last category:

We have felt compelled to give this catalogue in order that we might be able to know both these works and those that are cited by the heretics under the name of the apostles, including, for instance, such books as the Gospels of Peter, of Thomas, of Matthias, or of any others besides them, and the Acts of Andrew and John and the other apostles, which no one belonging to the succession of ecclesiastical writers has deemed worthy of mention in his writings. (“Eusebius on the Canon”).

How does Constantine figure into this? The documentary evidence tells us that what Constantine demanded of the bishops of Nicea in this regard was not an endorsement of a list of books he gave them. Rather, he demanded that Eusebius and the bishops produce “fifty copies of the Scriptures” for distribution throughout the empire. This demand, in effect, forced church authorities to land somewhere on the matter of which books were to form the New Testament. In response, church authorities decided to go with Eusebius’s list of undisputed books and those that were nearly undisputed. In effect, they chose a minimalist canon, one that nearly everyone in Christianity could agree upon. The rationale was that God had providentially directed the mass of believers toward consensus.

What do you think?
We have all sinned and deserve God’s judgment. God, the Father, sent His only Son to satisfy that judgment for those who believe in Him. Jesus, the creator and eternal Son of God, who lived a sinless life, loves us so much that He died for our sins, taking the punishment that we deserve, was buried, and rose from the dead according to the Bible. If you truly believe and trust this in your heart, receiving Jesus alone as your Savior, declaring, "Jesus is Lord," you will be saved from judgment and spend eternity with God in heaven.

What is your response?

Yes, I want to follow Jesus

I am a follower of Jesus

I still have questions

How can I know God

When you die, why should God let you into heaven?
