Can you define what a religion is?
Mohammed was not a prophet. Or can you point any prophecies he made? On the other hand, there are thousands of prophecies in the Bible. And it has a 100 accuracy. There is not a single prophecy in the Bible that has been proven wrong. That should tell you something.
I'm not asking which is the 'true' religion, I'm what is a religion.
So Mormonism, Islam, Hinduism, Buddhism, Shintoism, etc. are not religions because their founders were not 'true' messengers of the one true God?
