Christ is both the way and the door. Christ is the staircase and the vehicle, like the throne of mercy over the Ark of the Covenant, and the mystery hidden from the ages. A man should turn his full attention to this throne of mercy, and should gaze at him hanging on the cross, full of faith, hope and charity, devoted, full of wonder and joy, marked by gratitude, and open to praise and jubilation.
–Saint Bonaventure (1221-1274)
