I. One Must be Perfectly Holy to Enter Heaven
Job 4:17 Can mortal man be righteous before God? Can a man be pure before his Maker?
Job 25:4 How then can man be righteous before God? How can he who is born of woman be clean?
1 Corinthians 6:9-10 Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived; neither the immoral, nor idolaters, nor adulterers, nor sexual perverts, [10] nor thieves, nor the greedy, nor drunkards, nor revilers, nor robbers will inherit the kingdom of God.
Galatians 5:19-21 Now the works of the flesh are plain: fornication, impurity, licentiousness, [20] idolatry, sorcery, enmity, strife, jealousy, anger, selfishness, dissension, party spirit, [21] envy, drunkenness, carousing, and the like. I warn you, as I warned you before, that those who do such things shall not inherit the kingdom of God.
Ephesians 5:5 Be sure of this, that no fornicator or impure man, or one who is covetous (that is, an idolater), has any inheritance in the kingdom of Christ and of God.
Hebrews 12:14 . . . the holiness without which no one will see the Lord.
Hebrews 12:22-23 But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, [23] and to the assembly of the first-born who are enrolled in heaven, and to a judge who is God of all, and to the spirits of just men made perfect,
2 Peter 3:13 But according to his promise we wait for new heavens and a new earth in which righteousness dwells.
Revelation 21:27 But nothing unclean shall enter it, nor any one who practices abomination or falsehood, but only those who are written in the Lamb’s book of life.
Revelation 22:15 Outside are the dogs and sorcerers and fornicators and murderers and idolaters, and every one who loves and practices falsehood.
II. Prayers for the Dead in Purgatory
2 Maccabees 12:39-40, 42-45 On the next day, as by that time it had become necessary, Judas and his men went to take up the bodies of the fallen and to bring them back to lie with their kinsmen in the sepulchres of their fathers. [40] Then under the tunic of every one of the dead they found sacred tokens of the idols of Jamnia, which the law forbids the Jews to wear. And it became clear to all that this was why these men had fallen. . . . [42] and they turned to prayer, beseeching that the sin which had been committed might be wholly blotted out. . . . [43] He also took up a collection, man by man, to the amount of two thousand drachmas of silver, and sent it to Jerusalem to provide for a sin offering. In doing this he acted very well and honorably, taking account of the resurrection. [44] For if he were not expecting that those who had fallen would rise again, it would have been superfluous and foolish to pray for the dead. [45] But if he was looking to the splendid reward that is laid up for those who fall asleep in godliness, it was a holy and pious thought. Therefore he made atonement for the dead, that they might be delivered from their sin.
1 Corinthians 15:29 Otherwise, what do people mean by being baptized on behalf of the dead? If the dead are not raised at all, why are people baptized on their behalf?
Note: St. Francis de Sales (1567-1622), the great Catholic apologist and Doctor of the Church, exegeted this passage in the following way:
This passage properly understood evidently shows that it was the custom of the primitive Church to watch, pray, fast, for the souls of the departed. For, firstly, in the Scriptures to be baptized is often taken for afflictions and penances; as in St. Luke chapter 12 [12:50] . . . and in St. Mark chapter 10 [10:38-39] . . . in which places Our Lord calls pains and afflictions baptism [cf. Matthew 3:11, 20:22-3, Luke 3:16].
This then is the sense of that Scripture: if the dead rise not again, what is the use of mortifying and afflicting oneself, of praying and fasting for the dead? And indeed this sentence of St. Paul resembles that of 2 Maccabees 12:44 [“if he were not expecting that those who had fallen would rise again, it would have been superfluous and foolish to pray for the dead”]. (The Catholic Controversy, translated by Henry B. Mackey, Rockford, Illinois: TAN Books, 1989, from the 1886 edition (London and New York); originally 1596, 368).
2 Timothy 1:16, 18 May the Lord grant mercy to the household of Onesiph’orus, for he often refreshed me; he was not ashamed of my chains, . . . [18] may the Lord grant him to find mercy from the Lord on that Day — and you well know all the service he rendered at Ephesus.

V. The Nature and Experience of Direct Encounters with God
Exodus 3:5-6 Then he said, “Do not come near; put off your shoes from your feet, for the place on which you are standing is holy ground.” [6] And he said, “I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob.” And Moses hid his face, for he was afraid to look at God.
Exodus 34:29-30, 35 When Moses came down from Mount Sinai, with the two tables of the testimony in his hand as he came down from the mountain, Moses did not know that the skin of his face shone because he had been talking with God. [30] And when Aaron and all the people of Israel saw Moses, behold, the skin of his face shone, and they were afraid to come near him. . . . [35] the people of Israel saw the face of Moses, that the skin of Moses’ face shone; . . .
Deuteronomy 5:5, 24-26 while I stood between the LORD and you at that time, to declare to you the word of the LORD; for you were afraid because of the fire, and you did not go up into the mountain. . . . [24] and you said, `Behold, the LORD our God has shown us his glory and greatness, and we have heard his voice out of the midst of the fire; we have this day seen God speak with man and man still live. [25] Now therefore why should we die? For this great fire will consume us; if we hear the voice of the LORD our God any more, we shall die. [26] For who is there of all flesh, that has heard the voice of the living God speaking out of the midst of fire, as we have, and has still lived?
Deuteronomy 18:16 just as you desired of the LORD your God at Horeb on the day of the assembly, when you said, ‘Let me not hear again the voice of the LORD my God, or see this great fire any more, lest I die.’

[2] Above him stood the seraphim; each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew. [3] And one called to another and said: “Holy, holy, holy is the LORD of hosts; the whole earth is full of his glory.” [4] And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke. [5] And I said: “Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the LORD of hosts!”

[11] And Aaron said to Moses, “Oh, my lord, do not punish us because we have done foolishly and have sinned. [12] Let her not be as one dead, of whom the flesh is half consumed when he comes out of his mother’s womb.” [13] And Moses cried to the LORD, “Heal her, O God, I beseech thee.” [14] But the LORD said to Moses, “If her father had but spit in her face, should she not be shamed seven days? Let her be shut up outside the camp seven days, and after that she may be brought in again.”

[4] For though in the sight of men they were punished, their hope is full of immortality.

Romans 8:17-18 and if children, then heirs, heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him. [18] I consider that the sufferings of this present time are not worth comparing with the glory that is to be revealed to us.

[6] For the Lord disciplines him whom he loves, and chastises every son whom he receives.” [7] It is for discipline that you have to endure. God is treating you as sons; for what son is there whom his father does not discipline? [8] If you are left without discipline, in which all have participated, then you are illegitimate children and not sons. [9] Besides this, we have had earthly fathers to discipline us and we respected them. Shall we not much more be subject to the Father of spirits and live? [10] For they disciplined us for a short time at their pleasure, but he disciplines us for our good, that we may share his holiness. [11] For the moment all discipline seems painful rather than pleasant; later it yields the peaceful fruit of righteousness to those who have been trained by it.
James 1:12 Blessed is the man who endures trial, for when he has stood the test he will receive the crown of life which God has promised to those who love him.
1 Peter 1:4-7 and to an inheritance which is imperishable, undefiled, and unfading, kept in heaven for you, [5] who by God’s power are guarded through faith for a salvation ready to be revealed in the last time.

1 Peter 4:12 Beloved, do not be surprised at the fiery ordeal which comes upon you to prove you, as though something strange were happening to you.
1 Peter 5:10 And after you have suffered a little while, the God of all grace, who has called you to his eternal glory in Christ, will himself restore, establish, and strengthen you.
2 Peter 1:9 For whoever lacks these things is blind and shortsighted and has forgotten that he was cleansed from his old sins.
1 John 1:7-9 but if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin. [8] If we say we have no sin, we deceive ourselves, and the truth is not in us. [9] If we confess our sins, he is faithful and just, and will forgive our sins and cleanse us from all unrighteousness.
1 John 3:2-3 Beloved, we are God’s children now; it does not yet appear what we shall be, but we know that when he appears we shall be like him, for we shall see him as he is. [3] And every one who thus hopes in him purifies himself as he is pure.

1 Thessalonians 5:23 May the God of peace himself sanctify you wholly . . .
2 Thessalonians 2:13 . . . God chose you from the beginning to be saved, through sanctification by the Spirit and belief in the truth.
1 Peter 1:2 chosen and destined by God the Father and sanctified by the Spirit for obedience to Jesus Christ . . .
2 Peter 3:11, 14 Since all these things are thus to be dissolved, what sort of persons ought you to be in lives of holiness and godliness, . . . [14] Therefore, beloved, since you wait for these, be zealous to be found by him without spot or blemish, and at peace.

Summary: I collect 110 Bible passages that contain various elements of the doctrine of purgatory, including fire, cleansing, purifying, chastising, sanctification, prayers for the dead, etc.
