Yes, let's look. Here is what the Church believes, as can be found in the Catechism of the Catholic Church:
819 "Furthermore, many elements of sanctification and of truth" are found outside the visible confines of the Catholic Church: "the written Word of God; the life of grace; faith, hope, and charity, with the other interior gifts of the Holy Spirit, as well as visible elements." Christ's Spirit uses these Churches and ecclesial communities as means of salvation, whose power derives from the fullness of grace and truth that Christ has entrusted to the Catholic Church.
838 "The Church knows that she is joined in many ways to the baptized who are honored by the name of Christian, but do not profess the Catholic faith in its entirety or have not preserved unity or communion under the successor of Peter." Those "who believe in Christ and have been properly baptized are put in a certain, although imperfect, communion with the Catholic Church."
Catholicism adds to scripture and we know what that means.
True, the Church does not use Scripture exclusively, but also uses teachings of the Church handed down through the ages. The doctrine of sola scriptura itself is an addition to Scripture; and we all know what that means.
I would ask you not to twist my words
I did not twist your words. I simply posted that you said - that Cephas/Peter means rock.
You gotta be kidding me. Other churches get their power from the RCC? Ho boy!
>>Those "who believe in Christ and have been properly baptized are put in a certain, although imperfect, communion with the Catholic Church.<<
They are sanctimonious Ill give them that! I pity all who put their faith and trust in the RCC.
