(1Cor 3, 13) The work of each will come to light

[13] the work of each will come to light, for the Day will disclose it. It will be revealed with fire, and the fire (itself) will test the quality of each one's work.

(CCC 1030) All who die in God's grace and friendship, but still imperfectly purified, are indeed assured of their eternal salvation; but after death they undergo purification, so as to achieve the holiness necessary to enter the joy of heaven. (CCC 1031) The Church gives the name Purgatory to this final purification of the elect, which is entirely different from the punishment of the damned (Cf. Council of Florence (1439): DS 1304; Council of Trent (1563): DS 1820; (1547): 1580; see also Benedict XII, Benedictus Deus (1336): DS 1000). The Church formulated her doctrine of faith on Purgatory especially at the Councils of Florence and Trent. The tradition of the Church, by reference to certain texts of Scripture, speaks of a cleansing fire (Cf. 1 Cor 3:15; 1 Pet 1:7): As for certain lesser faults, we must believe that, before the Final Judgment, there is a purifying fire. He who is truth says that whoever utters blasphemy against the Holy Spirit will be pardoned neither in this age nor in the age to come. From this sentence we understand that certain offenses can be forgiven in this age, but certain others in the age to come (St. Gregory the Great, Dial. 4, 39: PL 77, 396; cf. Mt 12:31).
