Mary was an anointed young girl who found favor with God, and gave birth to our Savior. She went on to have other children with her husband, Joseph, thus making her a HUMAN BEING and not divine. I’m not sure how Catholics come up with the idea that she is part of the Godhead / Trinity, but she was not and is not. She was a human being who gave birth to our Lord — thus making Him able to be fully God and fully man simultaneously.
The Book of Mormon is a book written by a man who believed he was a Prophet, when in fact, he was not. God’s Word was given complete and in tact, with warnings (end of Revelation) against adding to, or taking away, from anything written before or after. Despite its history passed down through the ages, its authenticity and integrity remains faithful and stable. Praise God for a Creator who speaks clearly so we can understand Him, and so we can walk with Him and worship Him alone.
I, in turn, have no idea how people like you can allege, with an apparent, sincerely-held belief, that we Catholics believe such nonsense. You have been on this forum for nearly 2 years. If you had been paying even the slightest bit of attention, you would certainly know that your assertion, quoted above, is utterly false and slanderous. There are enough genuine differences of belief between us that you don't need to make-up others or perpetuate the clearly erroneous accusations of other ignorant people.
As for Mary's having other children or not, I would simply point out, at this late hour, that the issue is not nearly as cut-and-dried as you smugly suppose. There is room for honest people to have honestly varying opinions here, but I suspect that, just as you are so ignorant of Church teaching that you suppose we Catholics "worship" Mary as part of the "Godhead," it is equally likely that you haven't ever even bothered to barely look into Catholicism's reasons for asserting Mary's perpetual virginity, too. As you speak from ignorance on her status quite outside of the Godhead, you speak from ignorance while denying her virginity after Christ's birth. You do her and her Son insult, on at least two levels.
Mary had only one child, Jesus. Or was Jesus telling Mary to disown her other children when he said, “Here is THE son of yours” about John on the cross? Her only Son was dying on the cross, so he put her in the care of his beloved disciple. The article which I translate as “the” implies that there are no other. Yet you insist that James, et al are Jesus’ brothers?
The word translated commonly as “brother,” in fact, also refers to those cousins who are sons of an uncle.
Some biblical scholars have tried to take a “middle road” and interpret that James is a brother of Jesus, by a different mother, using Joseph’s legendary old age to suggest that Joseph was a widower. But, in fact, we know that James, Judas, Joses are brothers, and “of Clopus,” which is actually their hometown, not their father.
