Hi Sue,

This is a common question; it's even in our searchable knowledge base.

There are a lot of quick answers there, so give it a try.

I searched the knowledge base for you and found these web postings which should answer your question:

• Are there any examples I can use to point out that the term 'first born' was a common phrase?
• How do you interpret 'until' in Matthew and does this verse imply Joseph and Mary were intimate?
• Do you know of any resources that will help me explain (and defend) Mary's Virginity to my friend?
• What was the relationship between (James, Joseph, Simon, and Judas) to Our Lord, Jesus?
• Can you enlighten me and how do I rebut these phony claims that Jesus had brothers and sisters?
• and more.

If not, just come back and ask again.

You said:

• And if not, where in the Bible does it say this?

Your question implies a rejection of Catholic Oral Tradition which has been passed down to us by word of month. Unlike Sola Scriptura which depends solely on the Scriptures, Oral Tradition IS also biblical and does not depend solely on the Scriptures.

• The Biblical basis for Oral Tradition.
• The Biblical basis for Our Blessed Mother's Perpetual Virginity.
  

Hope this helps,

Mike
