Matthew 16:19
Douay-Rheims Bible
Christ to Peter
“And I will give to thee the keys of the kingdom of heaven. And whatsoever thou shalt bind upon earth, it shall be bound also in heaven: and whatsoever thou shalt loose upon earth, it shall be loosed also in heaven.”
That verse doesn’t mean that one mortal man can prevent another mortal man from salvation. The Bible spells out in many places what is “necessary for salvation” and it boils down to belief through faith and repentance. There is NOTHING in the Bible which says that any church is necessary for salvation or that doing any work, such as taking communion, is “necessary for salvation.”
Now I know the catechism of the Catholic church claims those things, but that just shows that the catechism isn’t in line with the Bible, so therefore, I don’t worry about what the catechism says.
