The Praise of the Father
Let those who falsely argue, that the Savior was not born but created, hear how Jesus calls His Father Lord of heaven and earth. For if our Lord was a creature, and the creature can call its Maker, Father, it was surely foolish here to address Him as Lord of heaven and earth, and not of Him (Christ) likewise. He gives thanks that His coming has opened to the Apostles sacraments, which the Scribes and Pharisees did not know, who seemed wise and understanding in their own eyes; "That you have hid these things from the wise and understanding and have revealed them to babes."
When Jesus says, "The wise", He does not speak of true wisdom, but of that which the Scribes and Pharisees seemed to have by their speech. Note that He did not say, 'And have revealed them to the foolish', but, to babes, that is, uneducated or simple; teaching us in all things to keep ourselves from pride, and to seek humility. The justice of this the Lord confirms by the sentence of the Father's will, that they who disdain to be made babes in God, should become fools in their own wisdom; and therefore He adds, "Even so, Father: for so it seemed good before you."
In the mutual knowledge between the Father and the Son, Jesus teaches us that there is nothing in the Son beyond what was in the Father; for it follows, And none knows the Son but the Father, nor does any man know the Father, but the Son. This mutual knowledge proclaims that they are of one substance since he that should know the Son, should know the Father also in the Son, since all things were delivered to Him by the Father.
