Now, consider: Christ frequently repeated that the Ten Commandments in the Pentateuch were to be followed, and He insisted that they should be maintained. Among the Ten Commandments is one which says: “Do not worship any picture or image."[ Cf. Exod. 20:4-5; Deut. 5:8-9] At present in some of the Christian churches many pictures and images exist. It is, therefore, clear and evident that the Religion of God does not maintain its original principles among the people, but that it has gradually changed and altered until it has been entirely destroyed and annihilated. Because of this the manifestation is renewed, and a new religion established. But if religions did not change and alter, there would be no need of renewal.
