en eauto katechon, hon dia tou baptismatos eilephe)" is able to see through the deceit of all heresies. Irenaeus here identifies the baptismal confession with what he calls the "rule of truth, kanon tes eiltheias" i.e., the truth which is the rule for everything claiming to be Christian. Apparently, this "rule of truth" was the sum of doctrines which every Christian received and confessed at his baptism. The very phrase "rule of truth" implies that it was a concise and definite formulation of the chief Christian truths. For "canon, rule," was the term employed by the ancient Church to designate such brief sentences as were adopted by synods for the practise of the Church. And this "rule of truth" is declared by Irenaeus to be "the old tradition," "the old tradition of the apostles": he te apo ton apostolon en te ekklesia paradosis. (Zahn, l.c., 379f.) Irenaeus was the pupil of Polycarp the Martyr; and what he had learned from him, Polycarp had received from the Apostle John. Polycarp, says Irenaeus, "taught the things which he had learned from the apostles, and which the Church has handed down, and which alone are true." According to Irenaeus, then, the "rule of truth" received and confessed by every Christian at his baptism was transmitted by the apostles. The contents of this rule of truth received from the apostles are repeatedly set forth by Irenaeus. In his Contra Haereses (I, 10, 1) one of these summaries reads as follows: "The Church dispersed through the whole world, to the ends of the earth has received from the apostles and their disciples the faith in one God, the Father Almighty, who has made heaven and earth and the sea and all things that are in them, and in one Jesus Christ, the Son of God, who became incarnate for our salvation; and in the Holy Spirit, who has proclaimed through the prophets the dispensations, and the advents, and the birth from a virgin, and the passion, and the resurrection from the dead, and the bodily assumption into heaven of the beloved Christ Jesus our Lord, and His manifestation from heaven in the glory of the Father." It thus appears that the "rule of truth" as Irenaeus knew it, the formulated sum of doctrines mediated by Baptism, which he, in accordance with the testimony of his teacher Polycarp, believed to have been received from the apostles, at least approaches our present Apostolic Creed.

11. Tertullian and Cyprian on Apostles' Creed.

A similar result is obtained from the writings of Tertullian, Cyprian, Novatian, Origen and others. "When we step into the water of Baptism," says Tertullian, who died about 220, "we confess the Christian faith according to the words of its law," i.e., according to the law of faith or the rule of faith. Tertullian, therefore, identifies the confession to which the candidates for Baptism were pledged with the brief formulation of the chief Christian doctrines which he variously designates as "the law of faith," "the rule of faith," frequently also as tessara, watchword and sacramentum, a term then signifying the military oath of allegiance. This Law or Rule of Faith was, according to Tertullian, the confession adopted by Christians everywhere, which distinguished them from unbelievers and heretics. The unity of the congregations, the granting of the greeting of peace, of the name brother, and of mutual hospitality,—these and similar Christian rights and privileges, says Tertullian, "depend on no other condition than the similar tradition of the same oath of allegiance," i.e., the adoption of the same baptismal rule of faith. (Zahn, 250.)

At the same time Tertullian most emphatically claims, "that this rule of faith was established by the apostles, aye, by Christ Himself," inasmuch as He had commanded to baptize "in the name of the Father, and of the Son, and of the Holy Ghost." (Zahn, 252.) In his book Adversus Praxeam, Tertullian concludes an epitome which he gives of "the rule of faith" as follows: "That this rule has come down from the beginning of the Gospel, even before the earlier heretics, and so, of course before the Praxeas of yesterday, is proved both by the lateness of all heretics and by the novelty of this Praxeas of yesterday." (Schaff, Creeds of Christendom, 2, 18.) The following form is taken from Tertullian's De Virginibus Velandis: "For the rule of faith is altogether one, alone (sola), immovable, and irreformable, namely, believing in one God omnipotent the Maker of the world, and in His Son Jesus Christ, born of the Virgin Mary, crucified under Pontius Pilate, raised from the dead the third day, received into the heavens, sitting now at the right hand of the Father who shall come to judge the living and the dead, also through the resurrection of the flesh." Cyprian the Martyr, bishop of Carthage, who died 257, and who was the first one to apply the term symbolum to the baptismal creed, in his Epistle to Magnus and to Januarius, as well as to other Numidian bishops, gives the following as the answer of the candidate for Baptism to the question, "Do you believe?": "I believe in God the Father, in His Son Christ, in the Holy Spirit. I believe the remission of sins, and the life eternal through the holy Church."

12. Variations of the Apostles' Creed.

While there can be no reasonable doubt either that the Christian churches from the very beginning were in possession of a definite and formulated symbol, or that this symbol was an amplification of the trinitarian formula of Baptism, yet we are unable to ascertain with any degree of certainty what its exact original wording was. There has not been found in the early Christian writers a single passage recording the precise form of the baptismal confession or the rule of truth and faith as used in the earliest churches. This lack of contemporal written records is accounted for by the fact that the early Christians and Christian churches refused on principle to impart and transmit their confession in any other manner than by word of mouth. Such was their attitude, not because they believed in keeping their creed secret, but because they viewed the exclusively oral method of impartation as the most appropriate in a matter which they regarded as an affair of deepest concern of their hearts.

It is universally admitted, even by those who believe that the apostles were instrumental in formulating the early Christian Creed, that the wording of it was not absolutely identical in all Christian congregations, and that in the course of time various changes and additions were made. "Tradition," says Tertullian with respect to the baptismal confession, received from the apostles, "has enlarged it, custom has confirmed it, faith observes and preserves it." (Zahn, 252. 381.) When, therefore, Tertullian and other ancient writers declare that the rule of faith received from the apostles is "altogether one, immovable, and irreformable," they do not at all mean to say that the phraseology of this symbol was alike everywhere, and that in this respect no changes whatever had been made, nor that any clauses had been added. Such variations, additions, and alterations, however, involved a doctrinal change of the confession no more than the Apology of the Augsburg Confession implies a doctrinal departure from this symbol. It remained the same Apostolic Creed, the changes and additions merely bringing out more fully and clearly its true, original meaning. And this is the sense in which Tertullian and others emphasize that the rule of faith is "one, immovable, and irreformable."

The oldest known form of the Apostles' Creed, according to A. Harnack, is the one used in the church at Rome, even prior to 150 A.D. It was, however, as late as 337 or 338, when this Creed, which, as the church at Rome claimed, was brought thither by Peter himself, was for the first time quoted as a whole by Bishop Marcellus of Ancyra in a letter to Bishop Julius of Rome, for the purpose of vindicating his
