Okay, well in short, I believe in the Holy Trinity. The Father, first of the Trinity, created the universe. Jesus, the second, is His son, and lived ~2,000 years ago as the embodiment of a Nazaren Jew. He died on the cross for our sins, and thus saved all of mankind. The Holy Spirit is the third of the Trinity, and provides guidance and protection for man, including inspiring writing the Bible.
My religion isn't absolute beyond that. Other Christian sects believe in worshiping saints directly, venerating relics or combining Jesus's teachings with voodoo or other supernatural traditions. Some others reject the Trinity and instead focus solely upon Jesus. While I can pass judgment on some of those, I do not know for sure if my religion is the purest either- perhaps we aren't as directly relatable to the teachings of Christ as we could be. My belief in a perfect being is one thing, though I know I'm not perfect.
