3. Now the words which stand at the beginning of the Psalm are quite unsuited to the Person and Dignity of the Son, while the whole contents are in themselves a condemnation of the careless haste that would use them to extol Him. For when it is said, and his will hath been in the Law of the Lord, how (seeing that the Law was given by the Son of God) can a happiness which depends on his will being in the Law of the Lord be attributed to Him Who is Himself Lord of the Law? That the Law is His He Himself declares in the seventy-seventh Psalm, where He says: Hear My Law, O My people: incline your ears unto the words of My mouth. I will open My mouth in a parable Ps. lxxvii. (lxxviii.) 1.. And the Evangelist Matthew further asserts that these words were spoken by the Son, when he says For this cause spake He in parables that the saying might be fulfilled: I will open My mouth in parables St. Matt. xiii. 35.. The Lord then gave fulfilment in act to His own prophecy, speaking in the parables in which He had promised that He would speak. But how can the sentence, and he shall be like a tree planted by the rills of water,—wherein growth in happiness is set forth in a figure—be possibly applied to His Person, and a tree be said to be more happy than the Son of God, and the cause of His happiness, which would be the case if an analogy were established between Him and it in respect of growth towards happiness? Again, since according to Wisdom Prov. viii. 22. and the Apostle, He is both before the ages and before times eternal, and is the First-born of every creature; and since in Him and through Him all things were created, how can He be happy by becoming like objects created by Himself? For neither does the power of the Creator need for its exaltation comparison with any creature, nor does the immemorial age of the First-born allow of a comparison involving unsuitable conditions of time, as would be the case if He were compared to a tree. For that which shall be at some point of future time cannot be looked upon as having either previously existed or as now existing anywhere. But whatsoever already is does not need any extension of time to begin existence, because it already possesses continuous existence from the date of its beginning up till the present.
