Various quibbling arguments, advanced by the Arians to show that the Son had a beginning of existence, are considered and refuted, on the ground that whilst the Arians plainly prove nothing, or if they prove anything, prove it against themselves, (inasmuch as He Who is the beginning of all cannot Himself have a beginning), their reasonings do not even hold true with regard to facts of human existence. Time could not be before He was, Who is the Author of time—if indeed at some time He was not in existence, then the Father was without His Power and Wisdom. Again, our own human experience shows that a person is said to exist before he is born.
