[Footnote 28: This supposition is based on observation of the fact that particular statements of the Roman Symbol, in exactly the same form or nearly so, are found in many early Christian writings. See Patr. App. Opp. I. 2, ed. 2, pp. 115-42.] [Footnote 29: The investigations which lead to this result are of a very complicated nature and cannot therefore be given here. We must content ourselves with remarking that all Western baptismal formulae (creeds) may be traced back to the Roman, and that there was no universal Eastern creed on parallel lines with the latter. There is no mistaking the importance which, in these circumstances, is to be attributed to the Roman symbol and Church as regards the development of Catholicism.] [Footnote 30: This caused the pronounced tendency of the Church to the formation of dogma, a movement for which Paul had already paved the way. The development of Christianity, as attested, for example, by the [Greek: Didache], received an additional factor in the dogmatic tradition, which soon gained the upper hand. The great reaction is then found in monasticism. Here again the rules of morality become the prevailing feature, and therefore the old Christian gnomic literature attains in this movement a second period of vigour. In it again dogmatics only form the background for the strict regulation of life. In the instruction given as a preparation for baptism the Christian moral commandments were of course always inculcated, and the obligation to observe these was expressed in the renunciation of Satan and all his works. In consequence of this, there were also fixed formulae in these cases.] [Footnote 31: See the Pastoral Epistles, those of John and of Ignatius; also the epistle of Jude, 1 Clem. VII., Polycarp, ad Philipp. VII., II. 1, VI. 3, Justin.]
