Do some research on the LIES told against the CATHOLIC CHURCH!
Plan by SATAN to remove Christ from a BILLION people!!
Lol. For this to be true you are assuming
1. People are in Christ
2. That leaving the Catholic church means you loose your salvation.
Both assumptions are obviously wrong.
Paul defined belonging to Christ is a position of FAITH, not which group you claim to belong to.
Jesus declaring He would build the church on Peters declaration, is saying it is the FAITH being expressed is the foundation of the church, not Peter the man, who died 2000 years ago. Peter never did found the Roman church, which only came into being because an Emporer declared the empire to be Christian by law, which is of itself a contradiction of the faith.
But all cults simplify the argument, with us, you are ok, against us, you are lost.
What Jesus said is follow Him, believe in Him you are ok, without Him you are lost. See the difference?
