Two that I like to visit and learn from. David Waltz is a former Jehovah’s Witness, Protestant, Roman Catholic – I am unsure of what church he goes to now, but he is very knowledgeable on church history and the early church fathers and historical theology.
I disagree with David Waltz on a lot of things, but he has a lot of great information on historical theology, church history, and the early church fathers.
A Roman Catholic blogger named Allan Ruhl.
I disagree with him on every issue of Protestantism vs. Roman Catholicism, but enjoy reading his blog, and appreciate many of his thoughts on moral issues and when he debates Muslims.
