The Church teaches us that the immortal soul of the human being receives a particular judgment where it can begin its purification process before being able to be before the presence of God, or either enter directly into the blessedness of Heaven, or immediately condemn itself forever (CCC 1022).
Although our destiny as Catholics who follow the teachings of our Lord Jesus Christ is that dwelling in the Kingdom of Heaven that our Lord has prepared for us (John 14:2). We gain that dwelling by following His teachings and fulfilling the sacraments that our Lord left us, especially with the sacrament of holy communion, through the Body and Blood of Jesus Christ, truly present in the consecrated host and wine, through which we will have eternal life. (John 6:53-54). If our sins do not allow us to fulfill this sacrament, let us first go to the Sacrament of Reconciliation, so that after sincere repentance they are forgiven, without forgetting to also comply with penance or reparation for them.
It is this last part that we must firmly comply with, since it is what allows us to enter directly into the presence of God when the time of our judgment arrives; failure to do so will lead our soul to a process of purification after death, in order to obtain the holiness necessary to be able to enter the joy of Heaven (CCC 1030).
It is also important to honor the memory of the deceased and offer suffrages in their favor, so that once purified, they can reach the beatific vision of God (CCC 1032). We can do this by dedicating masses and works of penance to them, as well as obtaining indulgences for the sanctification of the souls in purgatory.
Let us frequently participate in the Sacrament of Reconciliation, let us repent of all our sins, and faithfully carry out our penance so that we can share the glory with our Lord. Let us dedicate masses, works of penance and indulgences for the blessed souls in purgatory for their complete sanctification.
