what does the bible say?
All priests were Levites, but not all Levites were priests, since only the descendants of Aaron were appointed to the priesthood while the rest of the tribe assisted in tabernacle and temple duties (Numbers 3:5–10; 1 Chronicles 23:28–32). The priests had the unique role of offering sacrifices and mediating between God and Israel, even though they themselves were sinful and needed atonement (Leviticus 16; Leviticus 9:7). The other Levites supported this system by caring for the sacred space and its ministry but were not allowed to perform priestly sacrifices or enter the most holy functions (Numbers 3:5–9). This distinction highlighted both the holiness of God and the seriousness of sin. The priests and Levites showed that access to God required a qualified mediator. This entire system was fulfilled in Jesus Christ, our perfect and sinless High Priest who offered Himself once for all as the final sacrifice (Hebrews 7:27; 4:15–16). Because of Him, the barrier between us and God was removed so that all who trust in Him for the forgiveness of sins can draw near to God directly with confidence, no longer needing a human priestly mediator. The Old Testament priesthood, then, serves as a shadow pointing forward to the complete and finished work of Christ.
