I can understand that you believe in 1 only God (That's my faith too).But I can't understand why you don't belong to any religion since the holy books are from God and believing in them as being so is believing in God.I'm Muslim and proud to be,so I only believe in 1 God who is Allah and I believe in the Holy Quran and in our Prophet Muhammad peace and prayer be upon him,I also believe that other holy books got unfortunately falsified.
