The Profession of Faith 275 and helping our weakness by their fraternal concern” (Paul VI, CPG § 29). 1054 Those who die in God’s grace and friendship imper- fectly purified, although they are assured of their eter- nal salvation, undergo a purification after death, so as to achieve the holiness necessary to enter the joy of God. 1055 By virtue of the “communion of saints,” the Church commends the dead to God’s mercy and offers her prayers, especially the holy sacrifice of the Eucharist, on their behalf. 1056 Following the example of Christ, the Church warns the faithful of the “sad and lamentable reality of eternal death” ( GCD 69), also called “hell.” 1057 Hell’s principal punishment consists of eternal sepa- ration from God in whom alone man can have the life and happiness for which he was created and for which he longs. 1058 The Church prays that no one should be lost: “Lord, let me never be parted from you.” If it is true that no one can save himself, it is also true that God “desires all men to be saved” ( 1 Tim 2:4), and that for him “all things are possible” ( Mt 19:26). 1059 “The holy Roman Church firmly believes and con- fesses that on the Day of Judgment all men will appear in their own bodies before Christ’s tribunal to render an account of their own deeds” (Council of Lyons II : DS 859; cf. DS 1549). 1060 At the end of time, the Kingdom of God will come in its fullness. Then the just will reign with Christ for ever, glorified in body and soul, and the material universe itself will be transformed. God will then be “all in all” ( 1 Cor 15:28), in eternal life.
