We have thus reduced the six to four or three; and it is sometimes proposed to reduce the three to two, by identifying James the Lord's brother with James the son of Alphæus. But this identification is attended by difficulties so serious as to seem to be quite fatal; and it would probably never have been made but for the wish to show that "brother of the Lord" does not mean brother in the literal sense, but may mean _cousin_. For the identification depends upon making Mary the wife of Clopas (and mother of James the son of Alphæus) identical with the sister of Mary the mother of the Lord, in the much-discussed passage John xix. 25; so that Jesus and James would be first cousins, being sons respectively of two sisters, each of whom was called Mary.[17] The difficulties under which this theory labours are mainly these:-- 1. It depends on an identification of Clopas with Alphæus, which is uncertain, though not improbable. 2. It depends on a further identification of Christ's "mother's sister" with "Mary the wife of Clopas" in John xix. 25, which is both uncertain and highly improbable. In that verse we almost certainly have four women, and not three, contrasted with the four soldiers just mentioned (vv. 23, 24), and arranged in two pairs: "His mother, and His mother's sister; Mary the wife of Clopas, and Mary Magdalene." 3. It assumes that two sisters were both called Mary. 4. No instance in Greek literature has been found in which "brother" (ἀδελφός) means "cousin." The Greek language has a word to express "cousin" (ἀνεψιός), which occurs Col. iv. 10; and it is to be noted that the ancient tradition preserved by Hegesippus (c. A.D. 170) distinguishes James the first overseer of the Church of Jerusalem as the "_brother_ of the Lord" (Eus. _H. E._ II. xxiii. 1), and his successor Symeon as the "_cousin_ of the Lord" (IV. xxii. 4). Could Hegesippus have written thus if James were really a cousin? If a vague term such as "kinsman" (συγγενής) was wanted, that also might have been used, as in Luke i. 36, 58; ii. 44. 5. In none of the four lists of the Apostles is there any hint that any of them are the brethren of the Lord; and in Acts i. 13, 14, and 1 Cor. ix. 5, "the brethren of the Lord" are expressly distinguished from the Apostles. Moreover, the traditions of the age subsequent to the New Testament sometimes make James the Lord's brother one of the Seventy, but never one of the Twelve, a fact which can be explained only on the hypothesis that it was notorious that he was not one of the Twelve. The reverence for this James and for the title of Apostle was such that tradition would eagerly have given him the title had there been any opening for doing so.
