It was Constantine, the false Christian and Emperor of Rome, who founded the Catholic Church. According to Catholic tradition, he supposedly saw a message in the heavens, a blazing cross in the sky, which was said to be a promise from god to give him victory in his battle for political power in the Roman Senate. "In this sign conquer" it said, and so he went off to quickly 'convert' his thousands of soldiers with a flick of his wrist and a quick sprinkle of water - and conquered his own country by violence in what was essentially a coup.
It's funny how sometimes we miss the blatantly obvious, but it finally occurred to me today that "conquest" is not a Christ-like value. Neither is "evangelism" since the word literally means "waging war".
