The Jewish priesthood was a type of Christ fulfilled on the cross.. where Jesus was both Priest and sacrifice.. God destroyed the priesthood in 70 AD when the temple was destroyed ..the end of the priesthood type and the sacrifice types.
There was no priesthood in the NT church until the 300s when the mass became considered a "sacrifice"
How many times do we have to have this discussion? "Priest" (preost) is the Old English word for, and only for, presbuteros. The word for hiereus (the temple priest) was sacerd. The latter fell out of usage in Modern English and the English term for presbuteros (priest) was applied to hiereus. The difficulty is not that we are using the title of the temple priest for presbuteros but that we are using the title of presbuteros (priest) for hiereus.
