The quote from the Baltimore Catechism cited:
*If, then, we found a Protestant who never committed a mortal sin after Baptism, and who never had the slightest doubt about the truth of his religion, that person would be saved; because, being baptized, he is a member of the Church, and being free from mortal sin he is a friend of God and could not in justice be condemned to Hell. Such a person would attend Mass and receive the Sacraments if he knew the Catholic Church to be the only true Church. I am giving you an example, however, that is rarely found, except in the case of infants or very small children baptized in Protestant sects.
I do not speak here of pagans who have never heard of Our Lord or His holy religion, but of
those outside the Church who claim to be good Christians without being members of the Catholic Church. Catechism 4 question 121

Saint John Paul II in Ut Unum Sint:

[conclusion par. 17] At the conclusion of the Council, Pope Paul VI solemnly sealed the Council’s commitment to ecumenism, renewing the dialogue of charity with the Churches in communion with the Patriarch of Constantinople, and joining the Patriarch in the concrete and profoundly significant gesture which “condemned to oblivion” and “removed from memory and from the midst of the Church” the excommunications of the past.

- It happens for example that, in the spirit of the Sermon on the Mount, Christians of one confession no longer consider other Christians as enemies or strangers but see them as brothers and sisters. Again, the very expression separated brethren tends to be replaced today by expressions which more readily evoke the deep communion — linked to the baptismal character — which the Spirit fosters in spite of historical and canonical divisions. Today we speak of “other Christians”, “others who have received Baptism”, and “Christians of other Communities”. The Directory for the Application of Principles and Norms on Ecumenism refers to the Communities to which these Christians belong as “Churches and Ecclesial Communities that are not in full communion with the Catholic Church”. This broadening of vocabulary is indicative of a significant change in attitudes. There is an increased awareness that we all belong to Christ. I have personally been able many times to observe this during the ecumenical celebrations which are an important part of my Apostolic Visits to various parts of the world, and also in the meetings and ecumenical celebrations which have taken place in Rome. The “universal brotherhood” of Christians has become a firm ecumenical conviction.

[conclusion of par. 43] … I have thanked God “for what he has already accomplished in the other Churches and Ecclesial Communities and through them”, as well as through the Catholic Church. Today I see with satisfaction that the already vast network of ecumenical cooperation is constantly growing. Thanks also to the influence of the World Council of Churches, much is being accomplished in this field.

- The relationships which the members of the Catholic Church have established with other Christians since the Council have enabled us to discover what God is bringing about in the members of other Churches and Ecclesial Communities. This direct contact, at a variety of levels, with pastors and with the members of these Communities has made us aware of the witness which other Christians bear to God and to Christ. A vast new field has thus opened up for the whole ecumenical experience, which at the same time is the great challenge of our time. Is not the twentieth century a time of great witness, which extends “even to the shedding of blood”? And does not this witness also involve the various Churches and Ecclesial Communities which take their name from Christ, Crucified and Risen?
Such a joint witness of holiness, as fidelity to the one Lord, has an ecumenical potential extraordinarily rich in grace. The Second Vatican Council made it clear that elements present among other Christians can contribute to the edification of Catholics: “Nor should we forget that whatever is wrought by the grace of the Holy Spirit in the hearts of our separated brothers and sisters can contribute to our own edification.”

- In a theocentric vision, we Christians already have a common Martyrology. This also includes the martyrs of our own century, more numerous than one might think, and it shows how, at a profound level, God preserves communion among the baptized in the supreme demand of faith, manifested in the sacrifice of life itself. The fact that one can die for the faith shows that other demands of the faith can also be met. I have already remarked, and with deep joy, how an imperfect but real communion is preserved and is growing at many levels of ecclesial life. I now add that this communion is already perfect in what we all consider the highest point of the life of grace, martyria unto death, the truest communion possible with Christ who shed his Blood, and by that sacrifice brings near those who once were far off (cf. Eph 2:13).
While for all Christian communities the martyrs are the proof of the power of grace, they are not the only ones to bear witness to that power. Albeit in an invisible way, the communion between our Communities, even if still incomplete, is truly and solidly grounded in the full communion of the Saints—those who, at the end of a life faithful to grace, are in communion with Christ in glory.
These Saints come from all the Churches and Ecclesial Communities which gave them entrance into the communion of salvation*.
