Christ, in sending the [people] to the scriptures, sent them, not merely to read them, but carefully to search and ponder them. And did he not say, “Read the scriptures,” but “Search the scriptures.” … Their meaning is not expressed superficially or set forth in their literal sense, but, like a treasure, lies buried at a great depth. And those who seek for hidden things will not be able to find the object of the search if they do not seek carefully and painstakingly.
– St. John Chrysostom Homily 41 (John 5:39-47), A.D. 390
John Chrysostom (c. 347–407), Archbishop of Constantinople, was an important Early Church Father. He is known for his eloquence in preaching and public speaking, his denunciation of abuse of authority by both ecclesiastical and political leaders, the Divine Liturgy of St. John Chrysostom, and his ascetic sensibilities.
