we don't continually sacrifice Christ over and over
Neither do Catholics.
Luke 22:19 And He took bread, gave thanks and broke [it,] and gave [it] to them, saying, "This is My body which is given for you; do this in remembrance of Me." What is your justification for not doing this?
Regarding Luke 22:19 - we DO celebrate the Lord’s Supper. We do NOT however have the Doctrine of transubstantiation where the bread and the wine LITERALLY become the body and blood of Christ. That is more blasphemy.
