YOUCAT Question n. 53 - Part III. What is hell?

(Youcat answer - repeated) Our faith calls “hell” the condition of final separation from God. Anyone who sees love clearly in the face of God and, nevertheless, does not want it decides freely to have this condition instead.     

A deepening through CCC

(CCC 1073) The liturgy is also a participation in Christ's own prayer addressed to the Father in the Holy Spirit. In the liturgy, all Christian prayer finds its source and goal. Through the liturgy the inner man is rooted and grounded in "the great love with which [the Father] loved us" in his beloved Son (Eph 2:4; 3:16-17). It is the same "marvelous work of God" that is lived and internalized by all prayer, "at all times in the Spirit"  (Eph 6:18).       

Reflecting and meditating 

(Youcat comment) Jesus, who knows what hell is like, speaks about it as the “outer darkness” (Mt 8:12). Expressed in our terms, it is cold rather than hot. It is horrible to contemplate a condition of complete rigidity and hopeless isolation from everything that could bring aid, relief, joy, and consolation into one’s life.  

(CCC Comment)

(CCC 1036 b) Since we know neither the day nor the hour, we should follow the advice of the Lord and watch constantly so that, when the single course of our earthly life is completed, we may merit to enter with him into the marriage feast and be numbered among the blessed, and not, like the wicked and slothful servants, be ordered to depart into the eternal fire, into the outer darkness where "men will weep and gnash their teeth" (LG 48 § 3; Mt 22:13; cf. Heb 9:27; Mt 25:13, 26, 30, 31 46). [End]
