The opinion that the ἀδελφοὶ (brothers) and ἀδελφαὶ Ἰησοῦ (sisters of Jesus) mentioned in the New Testament, were merely half brothers or indeed cousins, appears in its origin, as shown above, together with the notion that no matrimonial connexion ever subsisted between Joseph and Mary, as the mere invention of superstition, a circumstance highly prejudicial to such an opinion. It is however no less true that purely exegetical grounds exist, in virtue of which theologians who were free from prejudice have decided, that the opinion that Jesus actually had brothers is untenable. [289] Had we merely the following passages—Matt. xiii. 55, Mark vi. 3, where the people of Nazareth, astonished at the wisdom of their countryman, in order to mark his well known origin, immediately after having spoken of τέκτων (the carpenter) his father, and his mother Mary, mention by name his ἀδελφοὺς (brothers) James, Joses, Simon, and Judas, together with his sisters whose names are not given [290]; again Matt. xii. 46, Luke viii. 19, when his mother and his brethren come to Jesus; John ii. 12, where Jesus journeys with his mother and his brethren to Capernaum; Acts i. 14, where they are mentioned in immediate connexion with his mother—if we had these passages only, we could not for a moment hesitate to recognize here real brothers of Jesus at least on the mother’s side, children of Joseph and Mary; not only on account of the proper signification of the word ἀδελφὸς, but also in consequence of its continual conjunction with Mary and Joseph. Even the passages—John vii. 5, in which it is remarked that his brethren did not believe on Jesus, and Mark iii. 21, compared with 31, where, according to the most probable explanation, the brothers of Jesus with his mother went out to lay hold of him as one beside himself—furnish no adequate grounds for relinquishing the proper signification of ἀδελφὸς. Many theologians have interpreted ἀδελφοὺς Ἰησοῦ in the last cited passage half brothers, sons of Joseph by a former marriage, alleging that the real brothers of Jesus must have believed on him, but this is a mere assumption. The difficulty seems greater when we read in John xix. 26 f. that Jesus, on the cross, enjoined John to be a son to his mother; an injunction it is not easy to regard as suitable under the supposition that Mary had other children, except indeed these were half-brothers and unfriendly to Jesus. Nevertheless we can imagine the existence both of external circumstances and of individual feelings which might have influenced Jesus to confide his mother to John rather than to his brothers. That these brothers appeared in company with his apostles after the ascension (Acts i. 14) is no proof that they must have believed on Jesus at the time of his death.
