Reformed Churches and Lutheran churches, and probably other Protestant churches believe in the real presence of Christ in the Eucharist.
Belief in the real presence does not make it so. There is a requirement of apostolic succession for Christ to be truly present.
There is only one body of Christ, thus my screen name of “One in Christ”.
The extent that other churches are in the Body of Christ is in direct correlation to the extent of their communion with the Catholic Church
This does not preclude salvation outside the church, see the CCC below and read the following paragraphs for more depth.
Who belongs to the Catholic Church?
836 "All men are called to this catholic unity of the People of God. . . . And to it, in different ways, belong or are ordered: the Catholic faithful, others who believe in Christ, and finally all mankind, called by God’s grace to salvation."320
837 "Fully incorporated into the society of the Church are those who, possessing the Spirit of Christ, accept all the means of salvation given to the Church together with her entire organization, and who - by the bonds constituted by the profession of faith, the sacraments, ecclesiastical government, and communion - are joined in the visible structure of the Church of Christ, who rules her through the Supreme Pontiff and the bishops. Even though incorporated into the Church, one who does not however persevere in charity is not saved. He remains indeed in the bosom of the Church, but ‘in body’ not ‘in heart.’"321
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."322 Those "who believe in Christ and have been properly baptized are put in a certain, although imperfect, communion with the Catholic Church."323 With the Orthodox Churches, this communion is so profound "that it lacks little to attain the fullness that would permit a common celebration of the Lord’s Eucharist."324
Suffering is a means of transforming us into the image of Christ. God allows or causes suffering for His purpose and our good.
Absolutely! Our priest gave a great homily last sunday about this. The fact that every time you are getting manure dumped on you it is not always punishment. Quite often it is simply God fertilizing our spiritual life through struggle. Testing by fire, so-to-speak.
