There is no such thing as an even minimally reasonable apologetic in favor of the Comma Johanneum. Despite five centuries to invent one, KJV Onlyists (or TR superiority advocates) have yet to be able to do so. If their argument is that John wrote this then they've had twenty centuries and yet their arguments are as weak today as when first proposed. Unfortunately, Dunkin demonstrates an incredible amount of ignorance (or deception) of the issue. Timothy's remarks will be in bold while my response will be in plain script.
