History of Purgatory is ever the same; "happiness and unhappiness" combined; both unspeakably great; long detention, perhaps, or perhaps swift release, according to the degree of faith and charity animating the Church militant. May we now, and henceforth, realize in act, in habitual practice, and, all the more, from the considerations given in the following pages, the immense privilege of holding, to so great a degree, the keys of Purgatory in our hands."] Believe it, it is one of the first rudiments, but main principles, of a Christian, to captivate his understanding, and so regulate all his dictamens, that they be sure to run parallel with the sentiments of the Church. And this I take to be the case when the question is started about Purgatory fire, which I shall ever reckon in the class of those truths, which cannot be contradicted without manifest temerity; as being the doctrine generally preached and taught all over Christendom. You must, then, conceive Purgatory to be a vast, darksome and hideous chaos, full of fire and flames, in which the souls are kept close prisoners, until they have fully satisfied for all their misdemeanors, according to the estimate of Divine justice. For God has made choice of this element of fire wherewith to punish souls, because it is the most active, piercing, sensible, [1] and insupportable of all others. But that which quickens it, indeed, and gives it more life, is this: that it acts as the instrument of God's justice, who, by His omnipotent power, heightens and reinforces its activity as He pleases, and so makes it capable to act upon bodiless spirits. Do not, then, look only upon this fire, though in good earnest it be dreadful enough of itself; but consider the Arm that is stretched out, and the Hand that strikes, and the rigor of God's infinite justice, who, through this element of fire, vents His wrath, and pours out whole tempests of His most severe and yet most just vengeance. So that the fire works as much mischief, [2] as I may say, to the souls, as God commands; and He commands as much as is due; and as much is due as the sentence bears: a sentence irrevocably pronounced at the high tribunal of the severe and rigorous justice of an angry God, and whose anger is so prevalent that the Holy Scripture styles it "a day of fury." Now, you will easily believe that this fire is a most horrible punishment in its own nature; but you may do well to reflect also on that which I have now suggested; that the fury of Almighty God is, as it were, the fire of this fire, and the heat of its heat; and that He serves Himself of it as He pleases, by doubling and redoubling its sharp pointed forces; for this is that which makes it the more grievous and insupportable to the souls that are thus miserably confined and imprisoned.
