The rest of the article explains about the inscription 'James, son of Joseph,brother of Jesus', and that through the test of scientists it is highly probable that this article is genuine. Even if scientists could 'prove it', my faith is not in the scientists but in the pure word of God (Ps 12:6,7). Matthew 13:55-56 - IS THIS NOT THIS THE CARPENTERS SON? IS NOT HIS MOTHER CALLED MARY? AND HIS BRETHREN, JAMES, AND JOSES, AND SIMON, AND JUDAS? AND HIS SISTERS,ARE THEY NOT ALL WITH US? WHENSE THEN HATH THIS MAN ALL THESE THINGS? This is all 'the proof' we need that Mary is not a perpetual version.
