Typical attempt at a “gotcha”…
The Catholic Encyclopedia(I at least have the integrity to mention my source before i post it):
Brethren of the Lord, the.—A group of persons closely connected with the Savior appears repeatedly in the New Testament under the designation “his brethren”, or “the brethren of the Lord” (Matt., xii, 46; xiii, 55; Mark, iii, 31, 32; vi, 3; Luke, 19, 20; John, ii, 12; vii, 3, 5; Acts, i, 14; I Cor., ix, 5). Four such “brethren” are mentioned by name in the parallel texts of Matt., xiii, 55, and Mark, vi, 3 (where “sisters” are also referred to), namely, James (also mentioned Gal., i, 19), Joseph, or Joses, Simon, and Jude; the incidental manner in which these names are given, shows, however, that the list lays no claim to completeness. Two questions in connection with these “brethren” of the Lord have long been, and are now more than ever, the subject of controversy: (I) The identity of James, Jude, and Simon; (2) The exact nature of the relationship between the Savior and his “brethren”.
(I) James is without doubt the Bishop of Jerusalem (Acts, xii, 17; xv, 13; xxi, 18; Gal., i, 19; ii, 9, 12) and the author of the first Catholic Epistle. His identity with James the Less (Mark, xv, 40) and the Apostle James, the son of Alpheus (Matt., x, 3; Mark, iii, 18), although contested by many Protestant critics, may also be considered as certain. There is no reasonable doubt that in Gal., i, 19: “But other of the apostles [besides Cephas] I saw none, saving James the brother of the Lord”, St. Paul represents James as a member of the Apostolic college. The purpose for which the statement is made, makes it clear that “apostles” is to be taken strictly to designate the Twelve, and its truthfulness demands that the clause “saving James” be understood to mean, that in addition to Cephas, St. Paul saw another Apostle, “James the brother of the Lord” (cf. Acts, ix, 27). Besides, the prominence and authority of James among the Apostles (Acts, xv, 13; Gal., ii, 9; in the latter text he is even named before Cephas) could have belonged only to one of their number. **Now there were only two Apostles named James: James the son of Zebedee, and James the son of Alpheus (Matt., x, 3; Mark, iii, 18; Luke, vi, 16; Acts, i, 13). **
The former is out of the question, since he was dead at the time of the events to which Acts, xv, 6 sqq., and Gal., ii, 9, 12, refer (cf. Acts, xii, 2). James “the brother of the Lord” is therefore one with James the son of Alpheus, and consequently with James the Less, the identity of these two being generally conceded. Again, on comparing John, xix, 25, with Matt., xxvii, 56, and Mark, xv, 40 (cf. Mark, xv, 47; xvi, 1),** we find that Mary of Cleophas, or more correctly Clopas (Kawaas), the sister of Mary the Mother of Christ, is the same as Mary the mother of James the Less and of Joseph, or Joses.** As married women are not distinguished by the addition of their father’s name, Mary of Clopas must be the wife of Clopas, and not his daughter, as has been maintained. Moreover, the names of her sons and the order in which they are given, no doubt the order of seniority, warrant us in identifying these sons with James and Joseph, or Joses, the “brethren” of the Lord. The existence among the early followers of Christ of two sets of brothers having the same names in the order of age, is not likely, and cannot be assumed without proof. Once this identity is conceded, the conclusion cannot well be avoided that Clopas and Alpheus are one person, even if the two names are quite distinct. It is, however, highly probable, and commonly admitted, that Clopas and Alpheus are merely different transcriptions of the same Aramaic word Halphai. James and Joseph the “brethren” of the Lord are thus the sons of Alpheus.
If you’re going to posit a passage of the Encyclopedia that “seems” to prove your point you must also agree with this passage as well.
