What the Bible says about Levi symbolic of church

Leviticus 7:31-32

Another aspect of this offering is important for us to consider more closely: The priest's children are also specifically named to receive of the peace offering. Compare this with Numbers 18:9-11:

This shall be yours of the most holy things reserved from the fire: every offering of theirs, every grain offering and every sin offering and every trespass offering which they render to Me, shall be most holy for you and your sons. In a most holy place you shall eat it; every male shall eat it. It shall be holy to you. This also is yours: the heave offering of their gift, with all the wave offerings of the children of Israel; I have given them to you, and your sons and daughters with you, as an ordinance forever. Everyone who is clean in your house may eat it.

Whom do the priest's children symbolically represent? This is important because they were also to eat directly of the offering and be satisfied. We have already seen that Christ is symbolically portrayed in several guises, as offerer, offering, and priest. Remember also that Christ is one with the church. We are parts of His body; we are "in Him."

The Old Testament also characterizes the church in several symbolic guises. For example, all of Israel represents the church as the children of God in pilgrimage to its inheritance. At other times, it is specifically represented as those who have made a covenant with God. Here, the priest's children—or at other times, the entire tribe of Levi—symbolize the church in another specific mode: in service to God. In being permitted to partake of the sacrifices, the priest's children stand for the church in communion with God. God shows through this that he who offered an animal in order to feast with God could not do so without also feasting with God's priests and their children.
