Remember that this is one of many things that we know from Tradition. That is usually meaningless to a NCC. To them, it’s like arguing that a touchdown is no good because the ball carrier missed second base. Or (for those who don’t know about American sports) that a goal is no good because the horse came in last.
If there was a verse in the NT that specifically says to ask the saints and/or Mary for their intercession, we’d have no problem proving that we’re right. The verses we do have are not that specific. They hint at it, rather than being definitive. The best we can do is to show that the Bible does not specifically forbid it.
Now for specifics. Bring your Catechism with you. The first thing in it should be the Apostolic Letter, Laetamur Magnopere. The second is the Apostolic Constitution, Fidei Depositum. Look at the end of that part, and highlight the part of this sentence that I have bolded:
- The Doctrinal Value of the Text
The Catechism of the Catholic Church, which I approved 25 June last and the publication of which I today order by virtue of my Apostolic Authority, is a statement of the Church’s faith and of catholic doctrine, attested to or illumined by Sacred Scripture, the Apostolic Tradition and the Church’s Magisterium.
Then put a bookmark there!
As a prologue, let them know that we use “praying to the saints” as an easy way to say “asking the saints to intercede for us.” It uses the word “pray” in its secondary meaning of “asking for a favor.”
First, ask where the Bible prohibits asking for the intercession of the saints. Ask them to be specific! Usually, the best they can come up with is in 1 Sam. 28. But you can use this chapter, too. Saul was using a medium (verse 7), not praying to Samuel for help.
Now, show them CCC 2116, which says that using mediums (and all other forms of divination) violates the commandment “You shall have no other gods before Me.” Tell them the Catechism is the doctrine of the Church; if they ask for proof, show them the part you highlighted about “doctrine.”
- Don’t get sidetracked by the subject of whose arrangement of the Commandments is better! Just nicely remind them that they asked about “praying to Mary and the saints.”
Now is the time to bring up the verses dmar198 gave us. Note that they do not prove that what we do is right - but they do show that talking to the angels and saints, and asking them to do something, is not wrong.
- A sidetrack that can arise here is that Rev. 5:8 shows that, of those who died after Jesus, only the “twenty-four elders” are in heaven. Some NCCs believe that our souls do not go to our eternal destination upon death, but will “sleep” until the Second coming. Again, nicely say that we’re talking about “praying to Mary and the saints,” not about the subject of “soul sleep.”
Also bring up Mark 9:4, as GardensWithKids suggested. It shows that Jesus, who was on earth at the time, conversed with someone known to be dead, that is, Moses. (Moses had a grave: Dt 34:5-6. Elijah didn’t: 2 Ki 2:11, so we can’t prove that he died.) Again, they can respond that only Jesus, who is God, spoke to them and the Apostles who saw it didn’t.
At the best, we can’t prove that the Bible tells us to ask for intercession by the people in Heaven. But unless you are dealing with someone unreasonable, you should be able to get them to admit that the Bible doesn’t specifically forbid it, either.
At the end of it all, you will probably not change their mind. But they may decide that you know your stuff, and bring you more questions. So you better know your stuff!
