Cyrill of Alexandria
It is evident that we do not serve God freely, as reiterated in the Scripture: “And when a priest offers anyone's burnt offering, the skin of the burnt offering which he offers belongs to the priest; and every offering of bread which is baked in the oven, and every offering which is cooked in a pot or in a pan, belongs to the priest who offers it; and every offering of bread mixed with oil and dry belongs to all the children of Aaron, both to the one and to the other” (Lev. 7:8-10). This principle is upheld within the Church, ensuring equality among the priests as they equally share the gifts of the unbloody sacrifice. Recognizing this, Paul states: “Do you not know that those who sacrifice are fed from the sanctuary?” highlighting the sustenance derived from the altar (1 Cor. 9:13-14). Furthermore, he notes that those who offer sacrifices “are not partakers of the altar,” as mentioned in another passage (1 Cor. 10:18). Indeed, as Palladius affirms, it is so.
