Mt 13, 55-56: "Is not this the carpenter‘s son? Is not his mother called Mary, and his brethren James, Joses, Simon and Judas? And his sisters, are they not all with us?"
As is well known, the Catholic Church interprets the word ‘brothers‘ as ‘cousins‘, but according to the New Revelation this is not correct at all. Although in Hebrew and Aramaic the word ‘ach‘ can mean either brother or cousin, nephew or member of the tribe, the Hebrew records of the New Testament writings have not been preserved and, therefore, the Greek text is binding. In Greek, however, brother is ‘adelphos‘ and cousin ‘anepsios‘, and in the New Testament the text in question includes the word ‘adelphos. The assumption that the translator has chosen a term which does not do justice to the Aramaic text is unacceptable. The New Revelation gives clear and exhaustive information on this subject.
In the Great Gospel vol. 11, p. 242 and in the work ‘The Childhood of Jesus‘ we are told that the brothers of Jesus were Joseph‘s sons from his first marriage. When Joseph married Mary he was already over 70 years of age and had been a widower for a long time. The ‘sisters‘ of Jesus were children of relatives of Joseph whom he had taken into his house as adopted children because of the great poverty of their parents. Therefore the people regarded them as sisters of Jesus, and the Evangelist reports correctly when he repeats verbally what the people said.
During the early Christian centuries church historians like Origen, Clemens of Alexandria, Epiphanes the Syrian and others did write about the fact that Joseph was a widower and had sons from his first marriage. In 383 A.D. the Bible translator Saint Jerome came up with the surmise that the so-called brothers of Jesus were actually cousins by relating this text to the words "his mother‘s sister, Mary, wife of Cleophas". (John 19, 25). "This construction by Saint Jerome", writes Arthur Schult, "which to this day is still generally accepted in Catholic circles, contradicts the plain text of the Gospels."
Thus there is no doubt that Jesus is the virgin Mary‘s one and only son.
