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.
