The Saint having turned to God the Father, explains why he does not deride that the Son is inferior to the Father, then he declares it is not for him to measure the Son of God, since it was given to an angel—nay, perhaps even to Christ as man—to measure merely Jerusalem. Arius, he says, has shown himself to be an imitator of Satan. It is a rash thing to hold discussions on the divine Generation. Since so great a sign of human generation has been given by Isaiah, we ought not to make comparisons in divine things. Lastly he shows how carefully we ought to avoid the pride of Arius, by putting before us various examples of Scriptures.
