Comment:
The assertion, that there is merely one true God, is contradicted by the testimony in paragraph 028-c which reads, "What have I to do with thee, Jesus, thou Son of God most high?" because one of the implications of this testimony is that there is at least one other god who is not most high. The assertion is further contradicted by the testimony in paragraph 125-f which reads, "I said, Ye are gods."
