The roman catholic mass is anti-biblical as it flies against Hebrews 10 which tells us one sacrifice has been offered for all sin. That is the death of Christ on the cross. For catholics to continue to insist He has to be re-sacrificed over and over again, as John O'Brien, a catholic priest has clearly stated, is a clear false teaching.
Christ said in John 5:24 that Truly, truly, I say to you, he who hears My word, and believes Him who sent Me, has eternal life, and does not come into judgment, but has passed out of death into life.
Even the disciples understood He was talking about belief in Him was the key as they noted in John 6:69, We have believed and have come to know that You are the Holy One of God.
Its seems to me that over and over the problem is that one ties God to time. Jesus was here in time and space as a physical human being but in his divine self he is God, without limits. It is His Body, Blood, Soul, and Divinity that I worship.
