Did anywhere I say that the Gospel came from the Catholic church?? No I did not. But ALL subsequent churches, after the formation of the Roman Catholic one, altered the Catholic bible. The Catholic Bible which has the same gospels in it as the Protestant one. And the Baptist one. And the Methodist one. And practically any other one you can find. Denominationalism is a stupid, stupid excuse for some 'Christians' to belittle, condemn and judge others as having 'a flawed faith'. What makes YOU so sure that YOURS is even correct? It's snobbery. Cut it out.
This is what you've been told to believe. How can you be so sure that those extra books were ever legitimate to begin with? You can't be. Afterall, Satan has never been able to destroy the bible but one thing he can do is corrupt it to lead people astray. You have a Catechism also, which is part of your Roman system.
Here is a thought for you...
1 Cor 2:14: "But the natural man does not receive the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they are spiritually discerned" - the bible is a spiritual book that can only be understood by born again believers because it's discerned only through the Spirit. Unless a person is spiritually born again they cannot understand th spiritual messages of the bible. They can understand the Gospel message as it is used to draw people by Faith to be saved. Only when a person is saved can they understand the bible and it's message. This is the truth. So all these people that have different interpretations of the bible - there is only one interpretation and it is discerned through the Spirit. You need the Spirit to understand.
The extra books are not Holy Spirit inspired. They were wrongfully added. The Spiritual messages in the bible all join together in unity and spell out the Gospel and instructions clearly. However, these extra books are like chalk compared with the cheese.
The reality is not everyone is saved. A person can say they are Christian but are they actually Christian? That is the question. Are you saved? I know I am. It's a supernatural experience, not a religious experience. One thing that happens when you're born again is you know you have eternal life. You have eternal security and know where you're going. You have a huge conviction of sins and I mean to the point where if you say something you realize it was a sin and feel incredibly bad about it and you're very sensitive to any sin in your life. You have a fear of God and naturally want to be obedient and do as He pleases. One thing that happened when I was born again - He took away my fear of the dark instantly, so I can happily walk around with no fear. I'm also very content. He filled a hole that I was trying to fill with other things. I am now complete and it's an amazing feeling that I don't need anything else. This among many many other things.
So, not everyone is Christian. On judgement say, many will say -
Matthew 7:21-23: "Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven. Many will say to Me in that day, ‘Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’"
