WHAT TO OFFER

If I renounce everything I possess, if I carry the cross and follow Christ, I have offered a holocaust on the altar of God. Or if I burn up my body in the fire of charity ..., I have offered a holocaust on the altar of God...; if I mortify my body and abstain from all concupiscence, if the world is crucified unto me and not me unto the world, then I have offered a holocaust on the altar of God and I am become a priest of my own sacrifice.

--Origen, In Lev. hom., 9, 9)
