“Only in the sense that Peter writes ALL believers are a kingdom of priests. “
Israel was said to be a priestly nation (Ex 19:6) yet it had a select priesthood. For Christians it is the same through Christ.
“Not in changed substance.”
Christ said it was changed in substance - Body and Blood, not bread and wine any longer.
“Not sacrifice perpetually.”
Re-presentation of one sacrifice - the sacrifice of Christ.
“Israel was said to be a priestly nation (Ex 19:6) yet it had a select priesthood. For Christians it is the same through Christ.”
The Church is the opposite of Israel - instead of descendants and tribes being the basis of serving as a priest, every believer in Christ is a priest.
“Christ said it was changed in substance - Body and Blood, not bread and wine any longer.”
He did not say it was the first time, but assuming He did for the sake of argument, He did not say it would be ever again. He said to do it in memory of Him.
“Re-presentation of one sacrifice - the sacrifice of Christ.”
Already presented the one and only time in heaven according to Hebrews. I suggest you review it.
Hebrews 9:12 - “Christ entered the ·Most Holy Place only once—and for all time. ·He did not take with him the blood of goats and calves. ·His sacrifice was his own blood, and by it he ·set us free from sin forever.”
