How do we know the priesthood ended with Christ's death?

The separation of the priesthood ended at the cross of Christ, highlighted in Hebrews 9:26, where it is stated that Christ appeared to put away sins by the sacrifice of Himself. This means that the need for a distinct order of priests, who offered daily sacrifices, was rendered obsolete upon the completion of Christ’s work on the cross. The New Testament church does not refer to any minister as a priest because that role has been fully executed by Christ, establishing that all believers share directly in the priesthood of Christ.
