To the objection of the Arians, that two Gods are introduced by a unity of substance, the answer is that a plurality of Gods is more likely to be inferred from diversity of substance. Further, their charge recoils upon themselves. Manifold diversity is the reason why two men cannot be said to be one man, though all men are called individually man, where a unity of nature is referred to. There is one nature alone in them, but there is wholly a unity in the Divine Persons. Therefore the Son is not to be severed from the Father, especially as they dare not deny that worship is due to Him.
