"All the fat is the LORD's. This is a lasting ordinance for the generations to come, wherever you live: you must not eat any fat or any blood." (Leviticus 3:16-17)
The fellowship offering, also translated peace offering or communion sacrifice, is distinct from the burnt offering in one crucial respect: the worshipper shares in the meal. The fat and blood belong to God; the priest receives a portion; the worshipper and their family eat the remainder. This is a sacrificial meal in the presence of God, a sharing of a table that bridges heaven and earth. The Catechism identifies the fellowship offering as the type of the Eucharistic meal: the sacrifice that becomes a shared meal, the community united around the altar by partaking together of what has been offered to God (CCC 1334).
The prohibition on eating fat or blood is absolute: All the fat is the LORD's. This is a lasting ordinance for the generations to come, wherever you live: you must not eat any fat or any blood. The fat, as the richest part of the animal, belongs entirely to God. The blood, as the seat of life, belongs to the God who gives life. These prohibitions encode a theology of creation: the best belongs to the Creator, and the life that courses through every creature is his. Kashrut, the Jewish dietary laws, preserves this reverence for life in every meal.
Brothers and sisters, the fellowship offering is a meal in God's presence, where the worshipper shares what has been sacrificed. Every Eucharist is this: the sacrifice and the meal are one. We do not merely observe the sacrifice from a distance; we eat and drink what has been offered, entering into communion with the one who was offered. Come to the table.
Lord God, all the fat is yours and all the life is yours. Receive our offering and invite us to your table. Let the fellowship offering of the Eucharist be the center of our week, the meal that makes us one with you and with each other. Through Christ our Lord. Amen.
