- The Old Testament Versus the New Testament: Do Christians Still Have to Observe OT Law?
- The History of the Debate
Most modern forms of Christianity accept the Old Testament and the New Testament. Where the two collections contradict each other many believe that the New Testament overrides the Old: this goes for parts that disagree directly on legalities (dietary codes, etc), and, the feel of God in the New Testament is accepted whereas the short-tempered and smiting god of the Old Testament is generally forgotten.
Some Christians argue that the "you" in Old Testament Law only refers to Jews. But they do not follow through with the line of logic, and they do not argue that the sins and new laws mentioned in the New Testament only apply to you Christians. And they also do not apply this logic to all of the Old Testament - just to the bits that they don't like. Also, there are New Testament verses (such as 2 Peter 3:1-2) which also state that the OT laws should be kept. So the reasoning against not having to obey the OT laws is inconsistent.
There are lots of verses in the Bible that imply that the Old Testament laws no longer need to be followed. But there are also a greater number of verses in the Bible that are very clear that all of God's laws are eternal and unchangeable, and apply "forever". So no matter which side of the argument you take, your actions and beliefs are not in accordance with what the Bible says. So, many preachers and teachers will select which set of verses they are going to quote from, and they manage to discount some of the opposing verses, and often, completely ignore the ones that they can't discount. Such confusing contradictions occur because the Bible was written by many different people, who all had different ideas and vested interests, and who wrote at different times and in different places. So on some theological points, such as whether or not everyone has to follow all the rules in the Bible or just the nice ones, there is no consistent message in the Bible.
The page linked above contains a long list of the verses, divided into those that state that the old law is eternal, and those that state that parts of it are now superceded.
