Speaking of Mark Shea, if you value the apologetics that he does for rock solid orthodoxy in the Catholic faith, please consider helping him out with a monetary donation. Folks like him--intelligent, articulate, orthodox--are hard to come by, and few are able to devote their full attention to apologetics the way he does. He is a witness not only to the content of our faith, but also to its appeal since, as a convert, he serves as a beacon to those are are struggling in other denominations. As a convert myself, I find his voice often to have a comforting ring to it.
I don't know Mark Shea from any context other than his blog, and I don't think he knows me at all--I don't think he even reads my blog, so I'm not doing this at his request or out of some sense of loyalty or payback. I just think he, and the cause, deserve it.
