First Christ is Lord of eternal Life. Full right to pass definitive judgment on the works and hearts of men belongs to him as redeemer of the world. He "aquired" this right by the cross. The Father has given "all judgments to the son". Yet the son did not come to Judge, but to save and give the life he has in himself. by rejecting graces in his life, one already judges oneself, receives according to one's works, and can even condemn oneself for all eternity y rejecting the Spirit of love
As sacrament, the Catholic Church is Christ's instrument. "She is taken up by hime also as the instrument for the salvation os all," "the Universal sacrament of salvation," by which Christ is "at once manifesting and actualizing the mystery os God's love for men." beacause God desire's "that the wholehuman race may become one People of God, form one body of Christ, and be built up into one temple of the Holy spirit."
Hell is the consquence of the continual rejection of God. the affirmations of Sacred Scrpture and the teaching of the Catholic Church on the subject of hell are a CALL TO THE RESPONSIBILITY incumbent upon man to make use of his freedom in view of his eternal destiny. they are at the same time an urgent CALL TO CONVERSION: "enter by the narrow gate; for the gate is wide and the way is easy, that leads to destruction, and those who enter by it are many . For the gateis narrow and the way is hard, that leads to life, and thosewho find it are few."
