4 Now this is a question which is often proposed by the most earnest brethren, and often has place in the conversation of the lovers of God's word; for this much knocking is wont to be made unto God, while men say, “Does the Father anything which the Son does not? Or does the Son anything which the Father does not?” Let us first speak of the Father and the Son. And when He to Whom we say, “Be Thou my helper, leave me not,” shall have given good success to this essay of ours, then shall we understand how that the Holy Spirit also is in no way separated from the operation of the Father and the Son. As concerning the Father and the Son, then, brethren, give ear. Does the Father anything without the Son? We answer, No. Do you doubt it? For what does He without Him “by Whom all things were made? All things,” says the Scripture, “were made by Him.” And to inculcate it fully upon the slow, and hard, and disputatious it added, And without Him was not anything made.
