Open your Bible and search the following passages:
Purgatory
Mt 5:48 - be perfect as your heavenly Father is perfect
Heb 12:14 - strive for that holiness without which cannot see God
Jam 3:2 - we all fall short in many respects
Rev 21:27 - nothing unclean shall enter heaven
Jam 1:14-15 - when sin reaches maturity gives birth to death
2Sam 12:13-14 - David, though forgiven, still punished for his sin
Mt 5:26 - you will not be released until paid last penny
Mt 12:32 - sin against Holy Spirit unforgiven in this age or next
Mt 12:36 - account for every idle word on judgment day
2Macc 12:44-46 - atoned for dead to free them from sin
1Cor 3:15 - suffer loss, but saved as through fire
1Pet 3:18-20; 4:6 - Jesus preached to spirits in prison
2Tim 1:16-18 - Paul prays for dead friend Onesiphorus
1Cor 15:29-30 - Paul mentions people baptizing for the dead
In 2 Tim, why is Paul praying for his dead friend? If his friend is in heaven he would need no prayers, yet, if his friend would be in hell prayers again are of no avail.
In 1 Peter, what prison is this? Could it be that Purgatory is this prison.
Most Protestants do not include the book of Maccabees...but, Catholics do. Here you will find again prayer for the dead.
Long before Christianity ... The Jews believed in a place our soul goes to before entering Heaven. Nothing unclean may enter Heaven. Keep in mind Jesus was Jewish. Did Jesus believe the Holy Scripture, of course he did.
The Catholic Bible is unchanged...even after 2,000 years. It holds many truths that have been lost or rejected by "Modern Christianity".
To add to your question reffered to Sparki:
Do you need to repent of sin? Of course you do. So, if you die with sin...what happens to you? Your "Unclean"...Nothing Unclean can enter Heaven...Purgatory is just as the name indicates...A place our soul is purged of all stain... So, that we may be worthy to enter Gods Kingdom.
Catholics believe we Must Repent of Our Sins.
"the Lord disciplines him whom he loves, and chastises every son whom he receives" (Heb. 12:6) — so some temporal penalties must remain.
The Church cannot wipe out, with a stroke of the pen, so to speak, everyone’s temporal punishments because their remission depends on the dispositions of the persons who suffer those temporal punishments. Just as repentance and faith are needed for the remission of eternal penalties, so they are needed for the remission of temporal penalties. Pope Paul VI stated, "Indulgences cannot be gained without a sincere conversion of outlook and unity with God"(Indulgentarium Doctrina 11). We might say that the degree of remission depends on how well the penitent has learned his lesson.
ADD: In Response to Heb 10:9-11
PAUL shares a similar perspective when he states, "Christ our paschal lamb has been sacrificed." (1 Cor. 5:7). Notice he does not conclude, "There is nothing more to be done." Instead, he says in the very next verse, "Let us, therefore, celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth" (1 Cor. 5:8). In other words, something more remains for us to do. We are to feast upon Jesus, the bread of life and our Passover Lamb.
Paul reinforces the reality of this communion elsewhere: "The cup of blessing which we bless, is it not a participation [koinonia] in the blood of Christ? The bread which we break, is it not a participation [koinonia] in the body of Christ?" (1 Cor. 10:16). Such language reflects a solid belief in the real presence of Christ in the Eucharist. No wonder Paul warns, "For any one who eats and drinks without discerning the body eats and drinks judgment upon himself" (1 Cor. 11:29).
I saw a similar outlook in the Epistle to the Hebrews. This came as a surprise, since I had always taught, as I had been trained, that Hebrews, more than any other New Testament book, contradicted the Catholic doctrine of the Eucharist as a sacrifice. The main theme of Hebrews is the priesthood of Jesus, particularly as it relates to his "once for all" sacrifice (Heb. 7:27; 9:12, 26; 10:10). This is succinctly stated: "Now the point in what we are saying is this: We have such a high priest, one who is seated at the right hand of the throne of the Majesty in heaven, a minister in the sanctuary and the true tabernacle which is set up not by man but by the Lord" (Heb. 8:1-2).
Unlike priests in the Old Testament, Jesus does not make daily offerings of distinct sacrifices (Heb. 7:27). On the other hand, "every high priest is appointed to offer gifts and sacrifices; hence it is necessary for this priest also to have something to offer" (Heb. 8:3). Does this mean that Jesus’ "once for all" sacrifice is exclusively past? Or does it not assert that Jesus’ sacrifice, precisely because of its "once for all" character, has become the one perfect and perpetual offering he continually presents in heaven on our behalf? The conclusion is that Jesus no longer bleeds, suffers, or dies (Heb. 9:25-26). He is enthroned in his resurrected and glorified human body as our High Priest and King (Heb. 7:1-3).
It is precisely in this manner that the Father beholds a perfect and perpetual offering in the living body of the Son. If Jesus’ offering has ceased, there would be no basis for his ongoing priesthood, but Jesus’ priesthood is said to be permanent and to "continue forever" (Heb.7:24). Moreover, there would be no reason for an earthly altar if Jesus’ offering is ended, which is what I believed as an Evangelical Protestant--until I discovered that Scripture teaches the reverse: "We have an altar from which those who serve the tent have no right to eat" (Heb. 13:10). The "once for all" character of Jesus’ sacrifice points to the perfection and perpetuity of his offering. It can be re-presented upon our altars in the Eucharist so that "through him [we] continually offer up a sacrifice of praise to God" (Heb. 13:15).
FINAL confirmation came for me when I came upon an exciting feature of John’s vision of Christ in the Book of Revelation. Upon hearing the angel announce the appearing of Jesus as "the Lion of the tribe of Judah," John looks and beholds "a Lamb standing, as though it had been slain" (Rev. 5:5-6).
In other words, he who is our celebrant priest and reigning king in the liturgical worship of the heavenly assembly also appears continually as the Passover Lamb of the New Covenant. He appears as the Lamb because his sacrificial offering continues. It will continue until he restores communion with each of his children through the Eucharist. Indeed, it will continue that way for God’s family forever into eternity. After all, our everlasting blessedness is depicted in John’s vision of the New Jerusalem as "the marriage supper of the Lamb" (Rev. 19:9, 21:2, 9-10, 22:17).
