Lets look at what the Church says on this issue.
First, from the Catechism of the Catholic Church in regards to people who are brought up in what are commonly called “protestant” Christian religions:
Quote:
818 “However, one cannot charge with the sin of the separation those who at present are born into these communities [that resulted from such separation] and in them are brought up in the faith of Christ, and the Catholic Church accepts them with respect and affection as brothers . . . . All who have been justified by faith in Baptism are incorporated into Christ; they therefore have a right to be called Christians, and with good reason are accepted as brothers in the Lord by the children 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. All these blessings come from Christ and lead to him, and are in themselves calls to “Catholic unity.”
Second, we are called to charity and love as Catholics. We can loose our salvation if we do not have charity for our fellow man.

DOGMATIC CONSTITUTION ON THE CHURCH, LUMEN GENTIUM, NOVEMBER 21, 1964**
Quote:
“Basing itself on scripture and tradition, it [the Council] teaches that the Church, a pilgrim now on earth, is necessary for salvation: the one Christ is mediator and the way of salvation; he is present to us in the body which is the Church…
“They are fully incorporated in the society of the Church who, possessing the Spirit of Christ, accept her entire system and all the means of salvation given to her, and are united with her as part of her visible bodily structure and through her with Christ, who rules her through the Supreme Pontiff and the bishops. The bonds which bind men to the Church in a visible way are profession of faith, the sacraments, and ecclesiastical governance and communion**. He is not saved, however, who, though part of the body of the Church, does not persevere in charity**. He remains indeed in the bosom of the Church, but, as it were, only in a ‘bodily’ manner and not ‘in his heart.’ All the Church’s children should remember that their exalted status is to be attributed not to their own merits but to the special grace of Christ. If they fail, moreover, to respond to that grace in thought, word and deed, not only shall they not be saved but they will be the more severely judged.”
Basically, “Judge not, that ye shall not be judged.”

Much of this seems contradictory to me.
On the one hand, I, a “Protestant,” through baptism, am incorporated into Christ and have the right (according to the RCC) to be called “
Christian” (this would not be the case, however, if I believed in Christ but was not baptized by water).
And, according to the CCC, I am, by your church, accepted as “
a brother in the Lord” even though I am not a member of the RCC, which, RC’ism considers to be “
the church.”
But according to the DOGMATIC CONSTITUTION ON THE CHURCH, LUMEN GENTIUM, NOVEMBER 21, 1964, “
the church” “is
necessary for salvation.”
So, Christ is the “
mediator” and “
way” of salvation but, according to the above quote, “
the church” is the
means of salvation and… “
they are fully incorporated in the society of the Church who…accept her entire system and all the means of salvation given to her.”
So, I, a “Protestant,” cannot be
incorporated in the society of “
the Church,” since I do not accept her “
entire system” and “
all the means of salvation given to her.”
So it seems to me, though accepted as a “
separated brother” I am accepted, however, as an unsaved brother in Christ, since I do not accept the “
entire system” with its
"means of salvation." Which I assume to be its seven sacraments.
And according to the above quote, the RC himself “
will be saved” (future) only if he/she perseveres in “
charity.”
Also, based on what has been expressed on this thread, am I a bona fide heretic if I
knowingly do not accept the “
entire system” of the RCC? If so, wouldn’t all “
separated brethren” who know and refuse to convert be considered heretics? And would we not all be classified as
unsaved heretics?
