Judaism Vs Christianity

In the last few weeks, we have been discussing Judaism and Christianity. Many people including myself have lumped Judaism and Christianity as one religion on many occasions due to their very similar set of beliefs. We just say “Oh, the only difference is that one is in the old testament and the other focuses on the new testament!’. But, we did not seem to (and most likely didn't care to) know about the differences in these two religions.

Even though this is done to most boys when they are a newborn due to health reason, it was first used as a sign of commitment and basically be a Jew. But, for Christianity even though Jesus was Jewish, John the baptist baptized him (that's where the baptist name came from) showing a sign of born again and second chance. So for Christians, they would usually get baptized to show their commitment to god.
Now, this is also a major difference between Judaism and Christianity. In the moral aspect, jews are more orthopraxy where they are more about the ethics of their religion instead of faith or grace. They follow the 613 commandments that were given to Moses from God. But, in Christianity, they focus more on the orthodoxy which is the opposite of orthopraxy since it deals with your faith and belief in god/ Jesus. With that being said, Christians will only follow the main 10 commandments that Moses and Jesus touch bases on the most. So to some jews, they would consider Christians as lazy due to them only following 10 out of 613 commandments which they believe are not true followers of the
