Not asserting, as Plato does, one to be intelligence,1 the other soul;2 for the Divine Nature is very different from this.… But you say, the Father is called God with the addition of the article, the Son without it. What say you then, when the Apostle. writes, The great God and our Saviour Jesus Christ; (Tit. 2:13) and again, Who is over all, God; (Rom. 9:5) and Grace be unto you and peace from God our Father; (Rom. 1:7) without the article? Besides, too, it were superfluous here, to affix what had been affixed just before. So that it does not follow, though the article is not affixed to the Son, that He is therefore an inferior God.
