John Chrysostom

Having said what we have come to, and showed the lovingkindness of God and the honor, by the greatness of the things given, he introduces yet another consideration that heightens them, namely, that neither before us did any one know Him. As he doth also in the Epistle to the Ephesians, saying, neither Angels, nor principalities, nor any other created power, but only the Son of God knew. And he said, not simply hid, but "quite hid," and that even if it hath but now come to pass, yet it is of old, and from the beginning God willed these things, and they were so planned out; but why, he saith not yet. "From the ages," from the beginning, as one might say. And with reason he calleth that a mystery, which none knew, save God. And where hid? In Christ; as he saith in the Epistle to the Ephesians, or as when the Prophet saith, "From everlasting even to everlasting Thou art." But now hath been manifested, he saith, "to His saints." So that it is altogether of the dispensation of God. "But now hath been manifested," he saith. He saith not, "is come to pass," but, "hath been manifested to His saints." So that it is even now still hid, since it hath been manifested to His saints alone.
