John Chrysostom

And what is, "anointed," and "sealed?" Gave the Spirit by Whom He did both these things, making at once prophets and priests and kings, for in old time these three sorts were anointed. But we have now not one of these dignities, but all three preeminently. For we are both to enjoy a kingdom and are made priests by offering our bodies for a sacrifice, (for, saith he, "present your members a living sacrifice unto God;) and withal we are constituted prophets too: for what things "eye hath not seen, nor ear heard," (1 Cor. ii. 9) these have been revealed unto us.
