What practice? Praying for dead? I am asking specifically about purgatory. Praying for dead does not constitute purgatory.
Sir, why pray for the dead if they are already in the blessed state in God's presence having received the reward of their faith and good deeds? One prays for the dead in the confidence that by means of our prayers they will receive the things we pray for from God's gracious hand. So we pray for the dead as the scriptures teach us to do because we are persuaded that those prayers matter and achieve their intended good in the lives of those for whom we say the prayers.
The Catholic Church teaches that, besides a place of eternal torments for the wicked and of everlasting rest for the righteous, there exists in the next life a middle state of temporary punishment, allotted for those who have died in venial sin, or who have not satisfied the justice of God for sins already forgiven. She also teaches us that, although the souls consigned to this intermediate state, commonly called purgatory, cannot help themselves, they may be aided by the suffrages of the faithful on earth. The existence of purgatory naturally implies the correlative dogma—the utility of praying for the dead—for the souls consigned to this middle state have not reached the term of their journey. They are still exiles from heaven and fit subjects for Divine clemency.
The doctrine of an intermediate state is thus succinctly asserted by the Council of Trent: “There is a Purgatory, and souls there detained, are helped by the prayers of the faithful, and especially by the acceptable Sacrifice of the Altar.
It is to be noted that the Council studiously abstains from specifying the nature of the expiating sufferings endured therein.
Is it not strange that this cherished doctrine should also be called in question by the levelling innovators of the sixteenth century, when we consider that it is clearly taught in the Old Testament; that it is, at least, insinuated in the New Testament; that it is unanimously proclaimed by the Fathers of the Church; that it is embodied in all the ancient liturgies of the Oriental and the Western church, and that it is a doctrine alike consonant with our reason and eminently consoling to the human heart?
First—It is a doctrine plainly contained in the Old Testament and piously practiced by the Hebrew people. At the close of an engagement which Judas Maccabeus had with the enemy he ordered prayers and sacrifices to be offered up for his slain comrades. “And making a gathering, he sent twelve thousand drachms of silver to Jerusalem for sacrifice to be offered for the sins of the dead, thinking well and religiously concerning the resurrection. For, if he had not hoped that they that were slain should rise again, it would have seemed superfluous and vain to pray for the dead.... It is, therefore, a holy and wholesome thought to pray for the dead, that they may be loosed from sins.”(2Macc. 12:43-46.)
These words are so forcible that no comment of mine could render them clearer. The passage proved a great stumbling-block to the Reformers. Finding that they could not by any evasion weaken the force of the text, they impiously threw overboard the Books of Maccabees, like a man who assassinates a hostile witness, or like the Jews who sought to kill Lazarus, lest his resurrection should be a testimony in Favor of Christ, and pretended that the two books of Maccabees were apocryphal. And yet they have precisely the same authority as the Gospel of St. Matthew or any other portion of the Bible, for the canonicity of the Holy Scriptures rests solely on the authority of the Catholic Church, which proclaimed them inspired.
But even admitting, for the sake of argument, that the Books of Maccabees were not entitled to be ranked among the canonical Books of Holy Scripture, no one, at least, has ever denied that they are truthful historical monuments, and as such that they serve to demonstrate that it was a prevailing practice among the Hebrew people, as it is with us, to offer up prayers and sacrifices for the dead.
