Scripture for that?
It worked for the first priests BEFORE He died and rose.
Which priests? The Jewish ones?
The Eucharistic Jesus dies and rises on the Altar.
Jesus said. *It is finished*. I don't know what Jesus you're worshiping but the one in Scripture, died (past tense), rose (past tense), and is seated at the right hand of God interceding for believers (present tense).
At the Last Supper Jesus says "this is my body"; that is before His death and resurrection and with His living natural body present; He also says "do it in memorial of me" (Luke 22:19), that would be after His death and resurrection. Golgotha is thereby, by His will, is made to be outside of time.
The Catholic priests, those who "do it in commemoration of Him" every day to this day.
