John 1:46

εὑρίσκει … Ναζαρέτ. Philip in turn finds Nathanael, probably on the road from the Bethany ford homewards. Nathanael is probably the same person as is spoken of in the Synoptical Gospels as Bartholomew, i.e., Bar Tolmai, son of Ptolemy. This is usually inferred from the following: (1) Both here and in chap. John 21:2 he is classed with apostles; (2) in the lists of apostles given in the Synoptical Gospels Bartholomew is coupled with Philip; (3) while Nathanael is never mentioned by the Synoptists, Bartholomew is not mentioned by John. The two names might quite well belong to one man, Bartholomew being a patronymic. Nathanael means “God's gift,” Theodore, or, like Augustine's son, Adeodatus. Philip announces the discovery in the words ὃν ἔγραψεν … Ναζαρέτ. On which Calvin remarks: “Quam tenuis fuerit modulus fidei in Philippo hinc patet, quod de Christo quatuor verba profari nequit, quin duos crassos errores permisceat. Facit ilium filium Joseph, et patriam Nazareth falso illi assignat.” This is too stringent. He draws the conclusion that where there is a sincere purpose to do good and to proclaim Christ, success will follow even where there is error. Nazareth lies due west from the south end of the Sea of Galilee, and about midway between it and the Mediterranean.
