Everything the Catholic Church professes and believes is found in Sacred Scripture and Sacred Tradition. In the Catechism of the Catholic Church purgatory is explained. . . . Specifically in these paragraphs: CCC 1030-32.
1 Cor:3:15 (But if someone's work is burned up, that one will suffer loss; the person will be saved, 8 but only as through fire.)
Mt 12:31 and
especially 2 Macc 12:46 (put it together with 1 Cor 3:15).
If purgatory doesn’t exist, why do we pray for the dead?
Mentions of hope for the dead is found in the bible. See Ruth 2:20; and 2 Macc 12:46 again.
People who leave the church because of dogmas and traditions not found in scripture means they fall into the same trap that fundamentalists do: that everything you need to know about salvation is found in the bible, or Sola Scriptura. Where is that in the bible? It doesn’t exist.
- 1Cor. 3:15
- But if someone's work is burned up, that one will suffer loss; the person will be saved, 8 but only as through fire.
8  Will be saved: although Paul can envision very harsh divine punishment (cf 1 Cor 3:17), he appears optimistic about the success of divine corrective means both here and elsewhere (cf 1 Cor 5:5; 11:32 [discipline]). The text of 1 Cor 3:15 has sometimes been used to support the notion of purgatory, though it does not *envisage this.
*en·vis·age - To conceive an image or a picture of, especially as a future possibility.
- 1 Peter 1-7
- so that the genuineness of your faith, more precious than gold that is perishable even though tested by fire, may prove to be for praise, glory, and honor at the revelation of Jesus Christ.
- Mt 12:31
- Therefore, I say to you, every sin and blasphemy will be forgiven people, but blasphemy against the Spirit 22 will not be forgiven.
- 22  Blasphemy against the Spirit: the sin of attributing to Satan (Matthew 12:24) what is the work of the Spirit of God (Matthew 12:28).
- 2 Macc 12:46
- Thus he made atonement for the dead that they might be freed from this sin.
- Ruth 2:20
- "May he be blessed by the LORD, who is ever merciful to the living and to the dead," Naomi exclaimed to her daughter-in-law; and she continued, "He is a relative of ours, one of our next of kin."
