Some of these errors the Christians go with too.
1. Christians believed the world was flat [well until man went into space]. I remember being in shock when discovering this verse in the Bible. A lot of non-Christians will refer to fundamentalist Christians as "flat-earthers" even.
Isaiah 40:22 It is he that sitteth upon the circle of the earth, and the inhabitants thereof are as grasshoppers; that stretcheth out the heavens as a curtain, and spreadeth them out as a tent to dwell in:
2 The world is 6,000 years old and the Bible says so. Actually it's not in there, though some say they calculated using the genealogical lists in the Bible. No verse points to this, there is nowhere in the Bible where it says the world is exactly 6,000 years old. I am open for discussion on this one. No I do not believe in evolution either. People don't realize that the one who came up with the 6,000 year mark was a Catholic Archbishop.!
3. God makes bad things happen. [The Calvinists run with this one] Yes God can use bad things for the good, but God is not the author of evil.
I meet so many unbelievers that do not get the simple concept that Satan is prince of this world, and that human sin opened this world to sin and death and that this affects all of us. They point to God saying, "He is the one at fault for thousands of children starving in world famines or for the problems I have faced in life" and turn their backs on Him in willful pride.
Romans 5:12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
4. The early church fathers taught truth. Early church "history", usually the facts handed down from Rome are wrong. The apostles themselves warned about EARLY GREVIOUS WOLVES, think about it, these people were there, the time they were alive, this is why no one should be impressed by someone saying that those early church fathers were honorable and true because they came right after the apostles.
Acts 20:29 For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.
Many believe Church history taught by Rome is legitimate, it is not. In fact if one dares to wipe away the Roman history and see things in the context of God's Word, instead of in false history mostly written by Rome where Constantine and pals come first and the church councils determine truth, then it is removing what I consider one of the giant blinders of all.
5. If you become a Christian it will make your life successful. I notice this even in more subtle fashions among fundamentalists and others, the thinking being if you become spiritually perfected that it will mean that your outside life will become a beacon of shining perfection to go with it. Real life on this earth is messy. The other day, I had the strange thought that the "best life now" stuff has infused way past liberal megachurch, and that holiness is supposed to make one's life more functional and "better". It doesn't always work that way. While God will give the Christian blessings, to be a Christian in this world can mean your life will be harder, whether you face out and out persecution or other smaller matters. One can ask, "What if my life is a mess and I am a Christian?" If you are not actively sinning, and trying to live right by God, life in this world can still be very hard. If you are poor, or people have walked away from you or you have had health and other losses, this does not mean you are a "bad" Christian. I wonder how many fall away on that one alone. Being a Christian is not a self improvement plan or a life-coaching seminar. If we even just take the apostles, some who died for the gospel, sitting in jail, via American standards is not being a "winner". It is by God's standards though, this is something to think about.
Add one of your own here, if you would like in comments. I think of the things even Christians take for granted and do not check in God's Word.
