What is the appeal of Roman Catholicism?

I have heard recently of folks converting from Protestantism to Roman Catholicism. I suppose this has been happening throughout the last 500 years, but it is probably more public now because of our instant-access media.

Anyway, the question should be asked, "For a Protestant, what is the appeal of Roman Catholicism?"

Tim Challies has addressed this issue very well. Click here to read his post. After reading the article, also take a look at the comments. It makes for good reading.
