You got it all wrong. Catholics have a Catechism where central truths handed down to St. Peter and the Apostles, by scripture, tradition and revelation are bound together as a unifying whole. A single Truth. There are NO many or different paths to salvations. If that were the case, the birth, death, and resurrection of the Christ would be pointless and would be seen as a superfluous alternative. We could all be Buddhists or Hindus.
No sir, there is but one Truth, and there cannot be 35,000 different variations of Christianity that Luther has spawned from the gospel of prosperity aka Joel Osteen to the gospel of socialism Rev. Wright. These Protestant denominations are nothing but wild mushrooming heresies.
I suggest you pick up a book by Hillaire Belloc “Heresy” and engage in some serious reading before venturing into deep waters.
Belonging to the Catholic church doesn't grant you access to God and not belonging to the Catholic church doesn't ban you from it.
There is only one "Christianity", and that is Jesus the Christ came as God in man, died for ALL mans sins, that all MIGHT know salvation and have access to God the Father.
That salvation comes through belief that Jesus is who he said he is, God the Son, and also that he died for our sins and ACCEPT him as Lord of their life.
My salvation is guaranteed and has no bearing on my position on the Catholic church.
Christ alone is more than enough.
