CIC 654 The Paschal mystery has two aspects: by his death, Christ liberates us from sin; by his Resurrection, he opens for us the way to a new life. This new life is above all justification that reinstates us in God’s grace, “so that as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life.”1 Justification consists in both victory over the death caused by sin and a new participation in grace.2 It brings about filial adoption so that men become Christ’s brethren, as Jesus himself called his disciples after his Resurrection: “Go and tell my brethren.”3 We are brethren not by nature, but by the gift of grace, because that adoptive filiation gains us a real share in the life of the only Son, which was fully revealed in his Resurrection.
CIC 1031 The Church gives the name Purgatory to this final purification of the elect, which is entirely different from the punishment of the damned.4 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:5
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.6
CIC 2627 Two fundamental forms express this movement: our prayer ascends in the Holy Spirit through Christ to the Father – we bless him for having blessed us;7 it implores the grace of the Holy Spirit that descends through Christ from the Father – he blesses us.8
