I'm sorry you think membership in your church is the key to salvation. There is nothing in Scripture proclaiming Roman Catholicism the way to salvation.
My Bible says:
John 3:16 For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
John 6:29 Jesus answered and said to them, "This is the work of God, that you believe in Him whom He sent."
Rom. 10:9 that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead you will be saved.
You can join us on this side of the Cross any time. Just believe The Gospel.
Following the teachings of Christ is the way to salvation and those teachings are taught and passed down in the Apostolic Church. if ones sub-sect of a sub-sect sees itself as having no common Gospel with The Church, then it falls into the same category as Mormons, Jehovahs Witnesses, etc. outside Christs Church and not Christian.
