In fact, it is not terrible to convert from Protestantism to Catholicism. After all, people still remain in the orthodox belief system. What is really worrying is the emergence of new radical religious sects such as Mormons, Jehovah’s Witnesses, and Almighty God. These sects are active and even a little extreme. They really like to poach people from orthodox religions to make its followers expanded rapidly. Therefore, just to preserve the orthodox belief system, the three major sects of Christianity must be united - at least spiritually. Only in this way can we suppress and isolate those even some mutated radical sects with an overwhelming numerical advantage.
