>>My belief is that we Catholics pray to the saints (and Mary) for intercession before the Lord. <<
The following is a sincere question: Since the Bible teaches that the Lord Jesus is our intercessor, why would we need some other saint (Mary or whomever) to be our intercessor? Also, as far as I can tell, when the word “saint” or “saints” appears in the bible, it is always referring to ALL believers, as opposed to a select few.
I suggest you actually read Scripture before you incorrectly paraphrase it.
