Aquinas on an important second subalternation of theology

"theology . . . has no direct evidence of the realities about which it speaks. The existence of God in his trinitarian mystery and all that he has accomplished for humankind in the history of salvation are evident to the eyes of God himself alone; if the blessed who see him face-to-face participate in the évidence of all of this [to God], we who are still on the way can have access to it only by and in faith. The subalternation of theology to the knowledge [1] that God has of himself and [2] that the blessed have of God is nothing other than a translation into technical language of the necessity of faith to the practice of theology."
