It was later that with the mixture of Mithraism, some Greek and Persian philosophies and stories of the time that the cult of Jesus became popular. Backed by the Roman Empire, the religions grew at a great speed often using force for conversion. It was only about 300 years ago that reformation started and one could freely question the basis.
