And so what is the mass, fundamentally, a banquet or a sacrifice?
It is a SACRIFICE, THE Sacrifice of Jesus Christ on the Cross, continuing down through the ages, re-presented in an unbloody manner by the hands of the priest, who is an
alter Christus.
The mass is not a “banquet”. That’s 1960’s-70’s garbage.
The priest and the people - who are
also priests, though unordained - offer Jesus
together, along with their very lives, to the Father, facing the same direction in their offering, which is a sign of their unity. The priest is also at the “head” of the people, as the primary minister offering Jesus to the Father.
That’s the way I see it.
From the CCC:
1366 The Eucharist is thus a sacrifice because it
re-presents (makes present) the sacrifice of the cross, because it is its
memorial and because it
applies its fruit:Christ, our Lord and God, was once and for all to offer himself to God the Father by his death on the altar of the cross, to accomplish there an everlasting redemption. But because his priesthood was not to end with his death, at the Last Supper “on the night when he was betrayed,” [he wanted] to leave to his beloved spouse the Church a visible sacrifice (as the nature of man demands) by which the bloody sacrifice which he was to accomplish once for all on the cross would be re-presented, its memory perpetuated until the end of the world, and its salutary power be applied to the forgiveness of the sins we daily commit.189 [from the Council of Trent]
