Catena Aurea on Matthew 11:27: Augustine of Hippo

When He said, “None knoweth the Son but the Father,” He did not add, And he to whom the Father will reveal the Son. But when He said, “None knoweth the Father bet the Son,” He added, “And he to whom the Son will reveal him.”

But this must not be so understood as though the Son could be known by none but by the Father only; while the Father may be known not only by the Son, but also by those to whom the Son shall reveal Him. But it is rather expressed thus, that we may understand that both the Father and the Son Himself are revealed by the Son, inasmuch as He is the light of our mind; and what is afterwards added, “And he to whom the Son will reveal,” is to be understood as spoken of the Son as well as the Father, and to refer to the whole of what had been said. For the Father declares Himself by His Word, but the Word declares not only that which is intended to be declared by it, but in declaring this declares itself.
