Origen

Or, when they allege secret and before unpublished Scriptures, in proof of their lie, they seem to say, Lo, the word of truth is in the desert. But when they produce canonical Scripture in which all Christians agree, they seem to say, Lo, the word of truth is in the chambers. Or wishing to point out such discourses as are altogether without Scripture, He said, If they shall say to you, Lo, he is in the secret chambers, believe it not. Truth is like the lightning that cometh out of the east, and shineth even unto the west. Or this may mean, that truth can be supported out of every passage of Scripture. The lightning of truth comes out of the east, that is, from the first beginnings of Christ, and shines throughout even to His passion, which is His setting; or from the very beginning of creation, to the last Scripture of the Apostles. Or, the east is the Law, the west is the end of the Law, and of John’s prophecy. The Church alone neither takes away word or meaning from this lightning, nor adds aught to its prophecy. Or He means that we should give no heed to those who say, Lo, here is Christ, but shew Him not in the Church, in which alone is the coming or the Son of Man, who said, Lo, I am with you always, even to the end of the world. (Mat. 28:20.)
