Genesis 5:22

Therefore, in this general and primordial law of God, the observance of which, in the case of the tree’s fruit, He had sanctioned, we recognise en closed all the precepts specially of the posterior Law, which germinated when dis closed at their proper times. For the subsequent superinduction of a law is the work of the same Being who had before premised a precept; since it is His province withal subsequently to train, who had before resolved to form, righteous creatures. For what wonder if He extends a discipline who institutes it? if He advances who begins? In short, before the Law of Moses, written in stone-tables, I contend that there was a law unwritten, which was habitually understood naturally, and by the fathers was habitually kept. …

IV. And if we must also look at ancient history, I perceive that Enoch, the seventh among our ancestors, was honoured by translation. I perceive also that the twenty-first, Abraham, was given the glory of the Patriarchate, by the addition of a greater mystery. For the Hebdomad thrice repeated brings out this number. And one who is very bold might venture even to come to the New Adam, my God and Lord Jesus Christ, Who is counted the Seventy-seventh from the old Adam who fell under sin, in the backward genealogy according to Luke. And I think of the seven trumpets of Jesus, the son of Nave, and the same number of circuits and days and priests, by which the walls of Jericho were shaken down. …

But if this could ever have literally happened how is it that it does not now also sometimes take place, and that we do not see some in the same way born of women by the agency of demons without intercourse with men? especially when it is clear that they delight in the pollution of lust, which they would certainly prefer to bring about through their own agency rather than through that of men, if they could possibly manage it, as Ecclesiastes declares: “What is it that hath been? The same that is. And what is it that hath been done? The same that is done. …

Serenus : God at man’s creation implanted in him naturally complete knowledge of the law, and if this had been kept by man, as at the beginning, according to the Lord’s purposes, there would not have been any need for another law to be given, which He afterwards proclaimed in writing: for it were superfluous for an external remedy to be offered, where an internal one was still implanted and vigorous. But since this had been, as we have said, utterly corrupted by freedom and the opportunity of sinning, the severe restrictions of the law of Moses were added as the executor and vindicator of this (earlier law) and to use the expressions of Scripture, as its helper, that through fear of immediate punishment men might be kept from altogether losing the good of natural knowledge, according to the word of the prophet who says “He gave the law to help them:” and it is also described by the Apost …
