And Jesus himself was about thirty years of age, being (as was supposed) the son of Joseph, who was the son of Heli,
All Commentaries on Luke 3:23 Go To Luke 3

AD 430
Or in another way; Matthew descends from David through Salomon to Joseph: but Luke beginning from Eli, who was in the line of our Savior, ascends through the line of; Nathan the son of David, and joins the tribes of Eli and Joseph, showing that they are both of the same family, and thereby that the Savior was not only the Son of Joseph, but also of Eli. For by the same reason by which the Savior is called the son of Joseph, he is also the son of Eli, and of all the rest who are of the same tribe. Hence that which the Apostle says, Of whom are the fathers, and from whom. Christ came according to the flesh.
Or there occur three reasons, by one of which the Evangelist was led. For either one Evangelist has mentioned the father by whom Joseph was, begotten, but the other his maternal grandfather, or some one of his ancestors. Or one of the fathers mentioned was the natural father of Joseph, the other his father who had adopted him. Or after the manner of the Jews, when aman has died without children, the next of kin taking his wife ascribes to his dead kinsman the son whom he has himself begotten.
It is most probable that Luke took the origin by adoption, as not being willing to say that Joseph, was begotten by him whose son he related him to be. For more easily is a man said to be his son by whom he was adopted, than to be begotten by him from whose flesh hewas not born. But Matthew saying, “Abraham begat Isaac, and Isaac begat Jacob,” and continuing in the word “begat,” until at last he says, but “Jacob begat Joseph,” has sufficiently expressed that he has carried through the succession of the fathers, to that father by whom Joseph was not adopted, but begotten. Although even supposing that Luke should say that Joseph was begotten by Eli, neither ought that word to perplex us. For it is not absurd to say that a man has begotten not in the flesh but in love the Son whom he has adopted. But rightly has Luke taken the origin by adoption, for by adoption are we made the sons of God, by believing on the Son of God, but by His birth in the flesh, the Son of God has rather for our sakes become the Son of man.
But it must be confessed that aprophet of this same name reproves David, that he might be thought to be the same man, whereas he was different.
He sufficiently declared by this that he called not Joseph the son of Eli because he was begotten by him, but rather because he was adopted by him, for he has called also Adam himself son, since though made by God, yet by grace (which he forfeited by sin) he was placed as a son in paradise.
Matthew indeed wished to set forth God descending to our mortality; accordingly at the beginning of the Gospel he recounted the generations from Abraham to the birth of Christ in adescending scale. But Luke, not at the beginning, but after the baptism of Christ, relates the generation not descending but ascending, as if marking out rather the high priest in the expiation of sins, of whom John bore testimony, saying, Behold, who takes away the sins of the world. But by ascending he comes to God, to whom we are reconciled, being cleansed and expiated.
But most fitly with regard to our baptized Lord does Luke reckon the generations through seventy-seven persons. For both the ascent to God is expressed, to whom we are reconciled by the abolition of sins, and by baptism is brought to man the remission of all hissins, which are signified by that number. For eleven times seven are seventy-seven. But by the tenth number is meant perfect happiness. Hence it is plain that the going beyond the tenth marks the sin of one through pride coveting to have more. But this is said to be seven times to signify that the transgression was caused by the moving of man. For by the third number the immortal part of man is represented, but by the fourth the body. But motion is not expressed in numbers, as when we say, one, two, three; but when we say, once, twice, thrice. And so by seven times eleven, is signified a transgression wrought by man's action.
