Either way, nothing is really proved. At best, it's a nice little historical tidbit to ooh and awe about, nothing more. My comment was a smarta$$ remark about all the anti-Catholics out there saying this "proves" the Church is wrong in teaching the perpetual virginity of Mary, the Mother of Jesus, and therefore the Mother of God. Of course, they'll attack anyway about anything for any reason...
Life goes on. The Church goes on.
