We have thus to see how, under the new conditions, faith passed beyond the moral stage, or simple trust in a person, to the metaphysical stage, or belief in certain propositions or technical definitions concerning Him, His nature, relations and actions. In this latter we may distinguish two correlated and interdependent phases or forms of belief, the one more intellectual and logical, the other more historical and concrete, namely, (1) the conviction that God being of a certain nature has certain attributes; (2) the conviction that, God being true, the statements which He makes through His prophets and ministers are also true.[670] The one of these forms of belief was elaborated into what we know as the Creed; the other, into the Canon of the New Testament. * * * * * We shall first deal with these phases or forms of belief, and then with the process by which the metaphysical definitions became authoritative. 1. In the first instance the intellectual element of belief was subordinated to the ethical purpose of the religion. Belief was not insisted upon in itself and for itself, but as the ground of moral reformation. The main content of the belief was “that men are punished for their sins and honoured for their good deeds:”[671] the ground of this conviction was the underlying belief that God is, and that He rewards and punishes. The feature which differentiated Christianity from philosophy was, that this belief as to the nature of God had been made certain by a revelation. The purpose of the revelation was salvation—regeneration and amendment of life. By degrees stress came to be laid on this underlying element. The revelation had not only made some propositions certain which hitherto had been only speculative, it had also added new propositions, assertions of its distinctive or differentiating belief. But it is uncertain, except within the narrowest limits, what those assertions were. There are several phrases in the New Testament and in sub-apostolic writings which read like references to some elementary statements or rule.[672] But none of them contain or express a recognized standard. Yet the standard may be gathered partly from the formula of admission into the Christian community, partly from the formulæ in which praise was ascribed to God. The most important of these, in view of its subsequent history, is the former. But the formula is itself uncertain; it existed at least in two main forms. There is evidence to show that the injunction to baptize in the name of the three Persons of the Trinity, which is found in the last chapter of St. Matthew, was observed.[673] It is the formula in the Teaching of the Apostles.[674] But there is also evidence, side by side with this evidence as to the use of the Trinitarian formula, of baptism into the name of Christ, or into the death of Christ.[675]
