And Jesus himself was about thirty years of age, being (as was supposed) the son of Joseph, who was the son of Heli,

Let us then more carefully explain the meaning of the words themselves. For if when Matthew affirmed Joseph to be the son of Jacob, Luke had in like manner affirmed that Joseph was the son of Eli, there would be some dispute. But seeing the case is that Matthew gives his opinion, Luke repeats the common opinion of many, not his own, saying, as was supposed, I do not think that there is any room for doubt. For since there were among the Jews different opinions of the genealogy of Christ, and yet all traced Him up to David because to him the promises were made, while many affirmed that Christ would come through Solomon and the other kings, some shunned this opinion because of the many crimes related of their kings, and because Jeremiah said of Jechonias that “a man should not rise of his seed to sit on the throne of David.” This last view Luke takes, though conscious that Matthew gives the real truth of the genealogy. This is the first reason. The next is a deeper one. For Matthew when he began to write of the things before the conception of Mary and the birth of Jesus in the flesh, very fitly as in a history commences with the ancestry in the flesh, and descending from thence deduces His generation from those who went before. For when the Word of God became flesh, He descended. But Luke hastens forward to the regeneration which takes place in baptism, and then gives another succession of families, and rising up from the lowest to the highest, keeps out of sight those sinners of whom Matthew makes mention, (because that he who is born again in God is separated from his guilty parents, being made the son of God,) and relates those who have led a virtuous life in the sight of God. For thus it was said to Abraham, You shall set out to your fathers, not fathers in the flesh, but in God, on account of their likeness in virtue. To him therefore who is born in God he ascribes parents who are according to God on account of this resemblance in character.
