PS, Crosswalk is one among many sites that use the KJV linked to Strong's numbers for Bible study of the original languages. (All I use at Crosswalk is the reference material there for Hebrew and Greek word pictures, because that's the method of Biblical inquiry I like right now, in addition to prayer, reflection, and discussion, and because I have not yet found software that does a good enough job on word pictures interlinearly for me to invest bucks in print references. I don't have much to say about the rest of the site, and I will not speak for them when anyone here can see how Crosswalk speaks for itself-- that is one reason people provide sources here when possible so readers can weigh the usefulness of the information or check into it further for themselves.

So it really doesn't matter what Crosswalk's purpose is, in the context of this discussion, although you can read all about it in their site material, if that's of interest to you.

The more relevant question might be, do Catholics use Strong's?
