Hello dangus.
To understand Calvary and Christ’s sacrifice, the book of Hebrews is crucial. I was raised RCC, but had to leave at about age 23 or 24, principally because of the Mass. The phrase “once for all”, as applied to the cross, occurs many times in Hebrews. Rather than amplify the importance of Jesus’ death on the cross, the Mass diminishes His once for all sacrifice. We therefore look to the Cross as a past event, with present and future benefit for those who believe and trust in Him.
Wow, Fishtank. I thought more of your understanding than to think you were still believing that old canard that Catholics believe that they are re-sacrificing Christ with every mass. I used “re-present” specifically to emphasize the point that there is only ONE Holy Sacrifice, separating “re” and “present” with that hyphen to avoid the confusion that I merely meant to metaphorically allude to something.
