Then Jesus is not dead nor has He risen from the dead. Then we are all in BIG trouble.
1 Corinthians 15:14-19 And if Christ has not been raised, then our preaching is in vain and your faith is in vain. We are even found to be misrepresenting God, because we testified about God that he raised Christ, whom he did not raise if it is true that the dead are not raised.
For if the dead are not raised, not even Christ has been raised. And if Christ has not been raised, your faith is futile and you are still in your sins. Then those also who have fallen asleep in Christ have perished. If in Christ we have hope in this life only, we are of all people most to be pitied.
When I was a catholic, I was told by the priests and nuns, that the mass was the unbloody sacrifice of the cross. We were told we were under the priests, who were in turn, under the pope. A chain of command, if you will. I understand that some others may have been told slightly different variations of this, but is that close to what you were told when you were catholics?
