Luke 3:38

Therefore Luke also thought that his origin should be traced back to God. Because God is the true Father of Christ, either the Father according to the true generation or the Author of the mystical gift—according to the regeneration of baptism. Furthermore, he did not start by describing his generation but first set forth his baptism. He desired to show him as God, the Author of all, weaving everything together through baptism. He also stated that Christ derived from God in the order of succession, in order to prove him the Son of God according to nature, according to grace and according to the flesh. Then what clearer evidence is there of divine generation than that before speaking of Jesus' generation, Luke has the Father himself saying, "This is my beloved Son, in whom I am well pleased"?

What could better agree than that the holy generation should commence from the Son of God, and be carried up even to the Son of God; and that he who was created should precede in a figure, in order that he who was born might follow in substance, so that he who was made after the image of God might go before, for whose sake the image of God was to descend. For Luke thought that the origin of Christ should be referred to God, because God is the true progenitor of Christ, or the Father according to the true birth, or the Author of the mystical gift according to baptism and regeneration, and therefore he did not from the first begin to describe His generation, but not till after he had unfolded His baptism, that both by nature and by grace, he might declare Him to be the Son of God. But what more evident sign of His divine generation than that when about to speak of it St. Luke introduces first the Father, saying, Thou art my beloved Son?

Who was Seth, who was Adam, who was of God. Because no iniquity of Christ, who had none, is of course joined with the iniquities of men, which he took upon himself in his flesh; therefore, the number according to Matthew, except for Christ, is forty. But because he unites us, cleansed and purged from all sin, to his own righteousness and that of his Father, as the Apostle says: "But he who is joined to the Lord is one spirit" (I Cor. VI), therefore in that number according to Luke, both Christ himself, from whom the enumeration begins, and God, to whom it leads, are included, and the number becomes seventy-eight, signifying the complete remission and abolition of all sins. For the Lord also made mention of this number when Peter asked him about forgiving a brother's sins. For he said: not only seven times, but seventy times seven must be forgiven (Matt. XVIII). Whence it is rightly believed that by the mention of this number, he ordered all sins to be forgiven. Nor did the Lord come in the seventieth and seventh generation to abolish all sins without reason or in vain, except because something lies hidden in that number which pertains to the signification of all sins. This is to be considered in the number eleven and seven. These numbers, when multiplied by each other, reach such an amount. For eleven times seven, or seven times eleven, make seventy-seven. But eleven signifies the transgression of ten. And if in ten is signified the perfection of blessedness, whence also it is that all those hired to the vineyard are rewarded with a denarius (Matt. XX), which happens when the seven-fold creature is joined to the Trinity of the Creator, it is clear that the transgression of ten signifies sin, by the proud desire of having something more and losing the integrity and perfection. This is multiplied by seven because that transgression made by the movement of man is signified. For the incorporeal part of man is signified by the number three. Whence it is that we are ordered to love God with all our heart, with all our soul, with all our mind (Mark XII). But the body is four; for many ways the nature of the body is found fourfold. Therefore, man, consisting of these combined, is not absurdly signified by the number seven. And movement is not expressed in numbers when we say one, two, three, four, etc., but when we say once, twice, thrice, four times. Accordingly…
