I like Richard Rohr. He's written some amazing stuff. His insights have helped me. But Rohr says some things that are provocative. He quotes nonChristians. When he sees something in another religion that is true, he'll use it to make a point.

So I received an email from someone who thinks this is a bad idea. They say that if you reference a person whose belief system is opposed to yours, then you've aligned yourself with that person. If the person quotes a New Ager, for example, then their credibility is suspect.

It got me thinking. Here's my question: If someone whose philosophy is very different than mine says something that is true, does that make the truth they've spoken any less true?

For example, let's say a Buddhist friend of mine said, "We men are conflicted and need peace. Generally speaking, we should build our lives around the things that bring us peace." Does the fact that he's a Buddhist invalidate what he says?

In court a judge will disallow the testimony of a person whose credibility is questionable. What about questions of faith - if a person's credibility is questionable, but they say something that is true, is the truth they spoke any less true?

In short, is all truth God's truth?
