Read Hebrews.
The sacrifice of the Lamb slain from the foundation of the world has been completed. God has accepted the offering for the sins of His flock.
There is no further sacrifice.
Rome somehow does not believe the first time was good enough. Apparently the sacrifice didn't stick. It must be repeated ad nauseum in contradiction to God's word.
And there are no priests in the New Testament. There is the priesthood of all believers and the one "high priest for ever after the order of Melchisedec," Jesus Christ.
There are teaching elders and pastors to preach the Gospel of Christ.
But there is no re-sacrifice. There are no "alter Christus."
Read your Bible and learn the truth. It will set you free, God willing.
Replying to each of your blurbs in order:
Yes the sacrifice has been completed in a sense, it still needs to be applied.
It is not a further sacrifice, it is making the original sacrifice present again through divinely instituted signs.
It is not a different time, it is not repeated, it is made present again.
The first clause of your second sentence contradicts your first sentence, but the main problem is overlooking the ¨do this in memory of me`thing.
There are greek words that are translated in a variety of ways, and certainly there are people with the responsibility of preaching, but this does not preclude the fact that the synoptics and first Corinthians make a big deal about representing the last supper explicitly, and John does the same in a more subtle manner.
No re-sacrifice—right, just a representation of the same sacrifice. Each individual sacramentally designated by Christ to represent Him IS an alter Christus. He who hears you hears me and all that. ARE is incorrect as Christus is singular.
And everything in the last statement is true, though with more elaboration, we probably could find something to disagree on.
