Cyprian, partly under other titles. Commodian, Arnobius, and Lactantius are also instructive here. This literature has been but little utilised with respect to the history of dogma and of the Church.

I. FIXING AND GRADUAL SECULARISING OF CHRISTIANITY AS A CHURCH

CHAPTER II

THE SETTING UP OF THE APOSTOLIC STANDARDS FOR ECCLESIASTICAL CHRISTIANITY. THE CATHOLIC CHURCH.²⁰

We may take as preface to this chapter three celebrated passages from Tertullian's "de præscriptione hæreticorum." In chap. 21 we find: "It is plain that all teaching that agrees with those apostolic Churches which are the wombs and origins of the faith must be set down as truth, it being certain that such doctrine contains that which the Church received from the Apostles, the Apostles from Christ, and Christ from God." In chap. 36 we read: "Let us see what it (the Roman Church) has learned, what it has taught, and what fellowship it has likewise had with the African Churches. It acknowledges one God the Lord, the creator of the universe, and Jesus Christ, the Son of God the creator, born of the Virgin Mary, as well as the resurrection of the flesh. It unites the Law and the Prophets with the writings of the Evangelists and Apostles. From these it draws its faith, and by their authority it seals this faith with water, clothes it with the Holy Spirit, feeds it with the eucharist, and encourages martyrdom. Hence it receives no one who rejects this institution." In chap. 32 the following challenge is addressed to the heretics: "Let them unfold a series of their bishops proceeding by succession from the beginning in such a way that this first bishop of theirs had as his authority and predecessor some one of the Apostles or one of the apostolic men, who, however, associated with the Apostles."²¹ From the consideration of these three passages it directly follows that three standards are to be kept in view, viz., the apostolic doctrine, the apostolic canon of Scripture, and the guarantee of apostolic authority, afforded by the organisation of the Church, that is, by the episcopate, and traced back to apostolic institution. It will be seen that the Church always adopted these three standards together, that is simultaneously.²² As a matter of fact they originated in Rome and gradually made their way in the other Churches. That Asia Minor had a share in this is probable, though the question is involved in obscurity. The three Catholic standards had their preparatory stages, (1) in short kerygmatic creeds; (2) in the authority of the Lord and the formless apostolic tradition as well as in the writings read in the Churches; (3) in the veneration paid to apostles, prophets, and teachers, or the "elders" and leaders of the individual communities.

A. The Transformation of the Baptismal Confession into the Apostolic Rule of Faith.

It has been explained (vol. I. p. 157) that the idea of the complete identity of what the Churches possessed as Christian communities with the doctrine or regulations of the twelve Apostles can already be shown in the earliest Gentile-Christian literature. In the widest sense the expression, κανων τησ παραδοσεως (canon of tradition), originally included all that was traced back to Christ himself through the medium of the Apostles and was of value for the faith and life of the Church, together with everything that was or seemed her inalienable possession, as, for instance, the Christian interpretation of the Old Testament. In the narrower sense that canon consisted of the history and words of Jesus. In so far as they formed the content of faith they were the faith itself, that is, the Christian truth; in so far as this faith was to determine the essence of everything Christian, it might be termed κανων της πιστεως, κανων της αληθειας (canon of the faith, canon of the truth).²³ But the very fact that the extent of what was regarded as tradition of the Apostles was quite undetermined ensured the possibility of the highest degree of freedom; it was also still allowable to give expression to Christian inspiration and to the intuition of enthusiasm without any regard to tradition.

We now know that before the violent conflict with Gnosticism short formulated summaries of the faith had already grown out of the missionary practice of the Church (catechising). The shortest formula was that which defined the Christian faith as belief in the Father, Son, and Spirit.²⁴ It appears to have been universally current in Christendom about the year 150. In the solemn transactions of the Church, therefore especially in baptism, in the great prayer of the Lord's Supper, as well as in the exorcism of demons,²⁵ fixed formulæ were used. They embraced also such articles as contained the most important facts in the history of Jesus.²⁶ We know definitely that not later than about the middle of the second century (about 140 A.D.) the Roman Church possessed a fixed creed, which every candidate for baptism had to profess;²⁷ and something similar must also have existed in Smyrna and other Churches of Asia Minor about the year 150, in some cases, even rather earlier. We may suppose that formulæ of similar plan and extent were also found in other provincial Churches about this time.²⁸ Still it is neither probable that all the then existing communities possessed such creeds, nor that those who used them had formulated them in such a rigid way as the Roman Church had done. The proclamation of the history of Christ predicted in the Old Testament, the κερυγμα της αληθειας, also accompanied the short baptismal formula without being expressed in set terms.²⁹

Words of Jesus and, in general, directions for the Christian life were not, as a rule, admitted into the short formulated creed. In
