If you follow beliefs from multiple religions, then you belong to your own religion.
dude, I myself is a Christian and I believe in Christian teachings but I still believe in some superstitions in my country, does it means that I'm not a christian because I mixed my belief with other beliefs?
you see, not all people believe in just ONE belief, they can always mix it with their own beliefs because you don't have to rely entirely on a book, you can also formulate your own reason and harmonize it with your religion.
