Hopefully, you believe Jesus is God. You don’t believe it, because Faith is a gift, pray about it and i am sure the Holy Spirit will lead you, just as Christians have been led from the time of the Apostles to the present. Reject this great apostasy doctrine. As to your Salvation, read John 6. The Church is the Body of Christ on earth, is there more than One Christ, if no, there is only One Body of Christ.
This n00b comes across more like a stealth Mormon trying to create an argument and thus confusion, than a Catholic Christian. Be cautious with this ‘one’ n00b.
Now you’re beginning to sounding like a mormon missionary. “Pray about it.”, “...great apostasy...”, “There’s only one [true] church.”.
Btw, since you’re a N00b, mindreading is against FR RF rules —”You don’t believe it,...”
Then they asked him, "What must we do to do the works God requires?"
Jesus answered, "The work of God is this: to believe in the one he has sent."
