It is a pleasure to observe the constant devotion of the Church of Christ in all ages, to pray for the dead. And first, to take my rise from the Apostles' time, there are many learned interpreters, who hold that baptism for the dead, of which the Apostle speaks, [1] to be meant only of the much fasting, prayer, alms-deeds, and other voluntary afflictions, which the first Christians undertook for the relief of their deceased friends. But I need not fetch in obscure places to prove so clear an Apostolical and early custom in God's Church.
[Footnote 1: Cor. xv 29.]
You may see a set form of prayer for the dead prescribed in all the ancient liturgies of the Apostles. [1] Besides, St. Clement [2] tells us, it was one of the chief heads of St. Peter's sermons, to be daily inculcating to the people this devotion of praying for the dead; and St. Denis [3] sets down at large the solemn ceremonies and prayers, which were then used at funerals; and receives them no otherwise than as Apostolical traditions, grounded upon the Word of God. And certainly, it would have done you good to have seen with what gravity and devotion that venerable prelate performed the divine office and prayer for the dead, and what an ocean of tears he drew from the eyes of all that were present.

Let Tertullian [1] speak for the next age. He tells us how carefully devout people in his time kept the anniversaries of the dead, and made their constant oblations for the sweet rest of their souls. "Here it is," says this grave author, "that the widow makes it appear whether or no she had any true love for her husband; if she continue yearly to do her best for the comfort of his soul." … Let your first care be, to ransom him out of Purgatory, and when you have once placed him in the empyrean heaven, he will be sure to take care for you and yours. I know your excuse is, that having procured for him the accustomed services of the Church, you need do no more for him; for you verily believe he is already in a blessed state. But this is rather a poor shift to excuse your own sloth and laziness, than that you believe it to be so in good earnest. For there is no man, says Origen, but the Son of God, can guess how long, or how many ages, a soul may stand in need of the purgation of fire. Mark the word ages; he seems to believe that a soul may, for whole ages—that is, for so many hundred years—be confined to this fiery lake, if she be wholly left to herself and her own sufferings.
[Footnote 1: Tertull. _De cor. mil. c 3; _De monogam, c. 10.]
It was not without confidence, says Eusebius, of reaping more fruit from the prayers of the faithful, that the honor of our nation, and the first Christian Emperor, Constantine the Great, took such care to be buried in the Church of the Apostles, whither all sorts of devout people resorting to perform their devotions to God and His Saints, would be sure to remember so good an emperor. Nor did he fail of his expectation; for it is incredible, as the same author observes, what a world of sighs and prayers were offered up for him upon this occasion.
St. Athanasius [1] brings an elegant comparison to express the incomparable benefit which accrues to the souls in Purgatory by our prayers. As the wine, says he, which is locked up in the cellar, yet is so recreated with the sweet odor of the flourishing vines which are growing in the fields, as to flower afresh, and leap, as it were, for joy, so the souls that are shut up in the centre of the earth feel the sweet incense of our prayers, and are exceedingly comforted and refreshed by it.
