But Luke has avoided the mention of these, that he might set forth the series of the priestly race immaculate. But the plan of St. Matthew did not exclude the righteousness of natural reason; for when he wrote in his Gospel, that He who should take on Him the sins of all, was born in the flesh, was subject to wrongs and pain, he did not think it any detraction from His holiness that He did not refuse the further humiliation of a sinful parentage.
Nor, again, would it shame the Church to be gathered from among sinners, when the Lord Himself was born of sinners; and, lastly, that the benefits of redemption might have their beginning with His own forefathers: and that none might imagine that a stain in their blood was any hindrance to virtue, nor again any pride themselves insolently on nobility of birth.
