Well, I hope one’s faith in Jesus is really true and one does not die in mortal sin. Even the Pharisees expressed faith in God, and you have read that Jesus told us not to be like them. Jesus will make a decision on justice at the date of our death.
Jesus told us to be humble like children, not like the Pharisees.
So if one does not believe in the Real Presence of Jesus Christ in the Eucharist, then does one have true faith in Jesus?
The Roman Catholic understanding of this does not align with the NT.
If your assertion is correct then everyone that Jesus talked to prior to the Bread of Life Discourse, and everyone else after that, in addition to Pentecost and the remainder of the NT, have been mislead. That is not the case.
Jesus spoke to Nicodemus and conveyed the message of believing in Him for salvation. There was no mention of the RC belief of the "Real Presence" or having to eat/drink the flesh/blood of Christ.
Nor was the RC belief the message that was conveyed on Pentecost.
Nor was Rome's message noted on Romans.
The NT is clear.....we come to salvation through faith in Christ.
Rome's concept of the "mortal sins" is also not found in the NT.
Paul is clear, as is the NT, that ALL sin, separates us from God.....apart from the forgiveness of sins through faith in Christ.
Further, some of your fellow Roman Catholics have conveyed the idea that having to participate in the "Mass", is not necessary after a "mortal sin".
I've asked the question...."what happens if you commit a "mortal sin" and die before you can get to the priest, confess, do penance and then the Mass?"
The answers I've received indicate if one is "contrite" in their heart then God will forgive the sin.
If what they say is correct, then the whole process Rome has determined is needed for forgiveness, is not needed.
The thief on the cross was without benefit of baptism and the eucharist and penance. Yet Jesus said he would be with Him in paradise.
The NT is clear, we come to faith in Christ Who forgives all of our sins.
