[Footnote 57: Hegesippus, who wrote about the time of Eleutherus, and was in Rome about the middle of the second century (probably somewhat earlier than Irenaeus), already set up the apostolic rule of faith as a standard. This is clear from the description of his work in Euseb., H. E. IV. 8. 2 ([Greek: en pente sungrammasin ten aplane paradosin tou apostolikou kerygmatos hypomnematisamenos]) as well as from the fragments of this work (l.c. IV. 22. 2, 3: [Greek: ho orthos logos] and Sec. 5 [Greek: emerisan ten henosin tes ekklesias phthorimaiois logois kata tou theou]; see also Sec. 4). Hegesippus already regarded the unity of the Church as dependent on the correct doctrine. Polycrates (Euseb., H. E. V. 24. 6) used the expression [Greek: ho kanon tes pisteos] in a very wide sense. But we may beyond doubt attribute to him the same conception with regard to the significance of the rule of faith as was held by his opponent Victor. The Antimontanist (in Euseb. H. E. V. 16. 22.) will only allow that the martyrs who went to death for the [Greek: kata aletheian pistis] were those belonging to the Church. The _regula fidei_ is not here meant, as in this case it was not a subject of dispute. On the other hand, the anonymous writer in Eusebius, H. E. V. 28. 6, 13 understood by [Greek: to ekklesiastikon phronema] or [Greek: ho kanon tes archaias pisteos] the interpreted baptismal confession, just as Irenaeus and Tertullian did. Hippolytus entirely agrees with these (see Philosoph. Praef., p. 4. v. 50 sq. and X. 32-34). Whether we are to ascribe the theory of Irenaeus to Theophilus is uncertain. His idea of the Church is that of Irenaeus (ad Autol. II. 14): [Greek: dedoken ho Theos to kosmo kumainomeno kai cheimazomeno hypo ton hamartematon tas synagogas, legomenas de ekklesias hagias, en ais kathaper limesin euormois en nesois hai didaskaliai tes aletheias eisin ... Kai hosper au nesoi eisin heterai petrodeis kai anudroi kai akarpoi kai theriodeis kai aoiketoi epi blabe ton pleonton ... houtos eisin hai didaskaliai tes planes, lego de ton haireseon, hai exapolluousin tous prosiontas autais.]]
