How can all religions be true?

Obviously they cannot all be true. Truth cannot conflict with truth. This applies not only to the completely different religions, but also to the thousands of conflicting denominations of Protestantism. The only way to identify a true religion is to make a list of those religions actually founded by God Himself, vs. those founded by men. Don't bother with the second list. It could take months to compile, and what good would it be? The first list will be much shorter. (1) Judaism, under God's Old Covenant with the human race. (2) The original Christian Church, the Catholic Church, under the New Covenant.
