I quickly read through that entire diatribe and did not see even one sentence defending your position or acknowledging the scriptures I provided. It was all just a bundle of assertions with no real usefulness.
I bet folks like that make fine priests for themselves, particularly when they can't even understand and accept that Christ is God Almighty and works totally outside of and apart from time.
Our sacrifice is ongoing because He is alive and interceding for us. Christ IS the sacrifice and therefore the sacrifice is ongoing, period. This moment, every moment, an everlasting sacrifice we partake of through the Eucharist. Of course, some people may believe that Christ is no longer alive, or isn't in heaven, or isn't constantly interceding for us, isn't God Almighty, or even that Christ lied when He said "This is my body". But, hey, such folks are by definition not Christian since they deny the diety of Christ.
