This passage has caused much trouble. Valesius remarks, “Africanus wishes to refer the words ὡς ἐνομίζετο (‘as was supposed’) not only to the words ὑιὸς ᾽Ιωσήφ, but also to the words τοῦ ῾Ηλὶ, which follow, which although it is acute is nevertheless improper and foolish; for if Luke indicates that legal generation or adoption by the words ὡς ἐνομίζετο, as Africanus claims, it would follow that Christ was the son of Joseph by legal adoption in the same way that Joseph was the son of Eli. And thus it would be said that Mary, after the death of Joseph, married his brother, and that Christ was begotten by him, which is impious and absurd. And besides, if these words, ὡς ἐνομίζετο, are extended to the words τοῦ ῾Ηλὶ, in the same way they can be extended to all which follow. For there is no reason why they should be supplied in the second grade and not in the others.” But against Valesius, Stroth says that Africanus seeks nothing in the words ὡς ἐνομίζετο, but in the fact that Luke says “he was the son of,” while Matthew says “he begat.” Stroth’s interpretation is followed by Closs, Heinichen, and others, but Routh follows Valesius. Spitta discusses the matter carefully (p. 91 sq.), agreeing with Valesius that Africanus lays the emphasis upon the words ὡς ἐνομίζετο, but by an emendation (introducing a second ὡς ἐνομίζετο, and reading “who was the son, as was supposed, of Joseph, the son of Jacob, who was himself also the son, as was supposed,—for this he also adds,—of Eli, the son of Melchi”) he applies the ὡς ἐνομίζετο only to the first and second members, and takes it in a more general sense to cover both cases, thus escaping Valesius’ conclusions expressed above. The conjecture is ingenious, but is unwarranted and unnecessary. The words which occur in the next sentence, “and the expression, ‘he begat’ he has omitted,” show that Africanus, as Stroth contends, lays the emphasis upon the difference of form in the two genealogies, “Son of” and “he begat.” The best explanation seems to me to be that Africanus supposes Luke to have implied the legal generation in the words “the Son of,” used in distinction from the definite expression “he begat,” and that the words ὡς ἐνομίζετο, which “he also adds,” simply emphasize this difference of expression by introducing a still greater ambiguity into Luke’s mode of statement. He not only uses the words, the “Son of,” which have a wide latitude, admitting any kind of sonship, but “he also adds,” “as was supposed,” showing, in Africanus’ opinion, still more clearly that the list which follows is far from being a closely defined table of descent by “natural generation.”
