I thought Catholics weren't particularly fond of Martin Luther. In fact, I've seen him condemned as antisemetic right here on FR. Tell me, are you standing against the anti Luther rhetoric?
Martin Luther was the first "protestant", it's ironic his beliefs have been diluted so much that many protestant churches have no regard or knowledge about his beliefs. Luther, along with most long standing Christian faiths, believe(d) in Mary as a perpetual Virgin and Blessed Mother. It's not just a Catholic "thing". Martin Luther divided the church, but I have no problem with that. Obviously God allowed it and His ways are not our ways. So to me Luther, like Judas, is simply a part of our church history and was possibly necessary for protecting His church.
If we are such a big target now, imagine what an easy target Christianity would be without all these thousands of little rogue mom and pop churches everywhere. Not to mention the Jehovah Witnesses and Hari Krishnas. God knows what He's doing. Although that is my personal opinion of Martin Luther, I don't any Catholics that have animosity towards him or protestants in general.
