Someone once remarked that it's not a miracle that Protestant error spread but that it actually stopped spreading as rapidly. Luther ushered "easy religion," with the rule "pecca fortiter" (sin forth!), assuring his followers to the effect that even if one commits adultery 300 times a day, God will forgive as long as you call on Jesus.
Doesn't get much easier than that!
Amen, brother. Preach it. The Way is wide and easy....
