I don't determine who goes to hell or heaven, I leave it up to God.
Yet the Catholic Church does determine who goes to hell or heaven.
Catholic Catechism, par. 870 "The sole Church of Christ which in the Creed we profess to be one, holy, catholic, and apostolic, . . . subsists in the Catholic Church, which is governed by the successor of Peter [i.e., the pope] and by the bishops in communion with him. Nevertheless, many elements of sanctification and of truth are found outside its visible confines'(LG 8).
Catholic Catechism, par. 846 How are we to understand this affirmation, often repeated by the Church Fathers? [Cf. Cyprian, Ep. 73.21: PL 3, 1169; De unit.: PL 4, 509-536.] Re-formulated positively, it means that all salvation comes from Christ the Head through the Church which is his Body: Basing itself on Scripture and Tradition, the Council teaches that the Church, a pilgrim now on earth, is necessary for salvation: the one Christ is the mediator and the way of salvation; he is present to us in his body which is the Church. He himself explicitly asserted the necessity of faith and Baptism, and thereby affirmed at the same time the necessity of the Church which men enter through Baptism as through a door. Hence they could not be saved who, knowing that the Catholic Church was founded as necessary by God through Christ, would refuse either to enter it or to remain in it. [LG 14; cf. Mark 16:16; John 3:5.]
1) "The holy universal Church proclaims that God cannot truly be worshipped save within herself, and asserts that all they who are without her pale shall never be saved."
Pope Gregory the Great 540-604 A.D.
2) "The Church is like the Ark of Noah, outside of which nobody can be saved."
St. Thomas Aquinas 1224-1274 A.D.
3) "That there is one Holy Catholic and apostolic Church we are compelled to believe and to hold, prompted by divine faith, and we do believe this firmly and confess it simply, outside of which there can be no salvation, or remission of sins…."
Pope Boniface VIII 1235-1303 A.D., became Pope in 1294
4) "It is a sin to believe that there is salvation outside the Catholic Church."
Pope Pius IX 1792-1878 A.D., became Pope in 1846, convened the first Vatican Council in 1869, which enunciated the Catholic doctrine of papal infallibility.
5) "We believe the Church is necessary for salvation because Christ, who is the sole mediator and exclusive way of salvation, renders Himself present for us in His body which is the Church. We must always remember the unity of the mystical body, without which there can be no salvation, is open to no one outside the Catholic Church."
Pope Paul VI 1897-1978 A.D. became Pope in 1963
6) "For it is through Christ’s Catholic Church alone, which is the universal help towards salvation, that the fullness of the means of salvation can be obtained."
Vatican II 1965
