The “Catholic Church” is all believers in Christ, universal, not just the ones who follow the bishop in Rome. I hope that you, indeed, are able to stand before the Father, and He can admit you to His kingdom because of what Christ did for you on the cross. THAT is what brings salvation, not adherence to any number of man-created doctrines...and that goes for Protestant man-made doctrines, too.
“Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in yourselves”
Unless you start participating in and believing those words above you will not inherit the Kingdom of Heaven. Why do protestants not believe the words of Jesus Christ?
Protestants broke away from the Catholic Church during the Reformation. So no protestants are not members of the Catholic Church. The Catholic Church is not a body of invisible Christian believers, some who never walk in the front door of church. Your deny the truth at your own peril.
