Semper Reformanda - the main idea is that we are always reforming. We can never allow ourselves to get bogged down in our traditions. We need to be open to what God's Word teaches us. So many times, Christians don't want to believe what the Bible shows is true. Why? Because they are stuck in their traditions. Their church always told them this, but the Bible says that. Surely the Bible can't be contradicting what their pastor told them. But of course it can - pastors are fallible men; the Bible is the perfect Word of God. But people get so caught up in traditions of men. You tell them this, and they say they have no traditions. But as James R. White says "It's those who claim to have no traditions that are most enslaved by them."
