There are
two apostles named "James": James the Great,
son of Zebedee, and
brother of apostle John (Mat. 4:19-22, Mk. 1:19-20, Mk. 3:14-18, Mk. 10:35, Lk. 5:10-11), and James the Less,
son of Alphaeus, and
brother of apostle Judas (Thaddeus) (Mat. 10:2-3, Mk. 3:14-18, Lk. 6:15-16, Ac. 1:13). One of those "James's" is also identified as a
brother of Jesus (Gal. 1:19). Elsewhere, there is a "James" identified as a
son of Mary, and
brother of Joseph (Mat. 27:56, Mk. 15:40), and a
brother of Simon, Joseph, Judas (Thaddeus), and Jesus (Mat. 13:55-56, Mk. 6:3).
Furthermore, the Blessed Virgin's
sister, Mary, was the wife of Cleophas/Clopas (Jn. 19:25), and the names "Cleophas", and "Clopas", are variants of the name "Alphaeus". Additionally, Eusebius of Caesarea (AD 275 – 339) relates in his
Church History (Book III, ch. 11) that Hegesippus records that St. Joseph had a brother named Clopas (Alphaeus). In
The Poem of the Man-God: Volumes I-V, by Maria Valtorta, Jesus confirms St. Joseph had a brother named "Alphaeus", who was also married to a woman named "Mary", who together had four sons: Simon, Joseph, and the apostles James, and Judas (Thaddeus). This would make the Blessed Virgin's sister, Mary, more accurately Her sister-
in-law, and the latter's sons Jesus's
cousins.
Note: the word "brother" (
ἀδελφός, Adelphos), has a range of meanings, including "a pers. viewed as a brother in terms of a close affinity".
In summary, at minimum, there is strong scriptural evidence to support the following pair of individuals are one and the same: (i) James
of Alphaeus, and the "James" in Mat. 13:55-56, Mk. 6:3, and Gal. 1:19, and (ii) James's mother, Mary, and the Blessed Virgin's sister, Mary. This debunks your claim Simon, Joseph, James, and Judas (Thaddeus), were
of St. Joseph, and the Blessed Virgin, thus the meaning "a male from the same womb" of the word "brother", in all the aforementioned verses in relation to Jesus, does not apply.
