Purgatory Denies the Sufficiency of the Cross of Christ

The Bible does not teach purgatory.  Rather it teaches the sufficiency of the Cross of Jesus.  Jesus is the only Person who was able to endure the redemptive suffering of the Cross.  Rome believes that punishment through purgatory can purify us through divine flames.  For lets understand the Roman position,

1031 The Church gives the name Purgatory to this final purification of the elect, which is entirely different from the punishment of the damned. The Church formulated her doctrine of faith on Purgatory especially at the Councils of Florence and Trent. The tradition of the Church, by reference to certain texts of Scripture, speaks of a cleansing fire: As for certain lesser faults, we must believe that, before the Final Judgment, there is a purifying fire. He who is truth says that whoever utters blasphemy against the Holy Spirit will be pardoned neither in this age nor in the age to come. From this sentence we understand that certain offenses can be forgiven in this age, but certain others in the age to come.

1498 Through indulgences the faithful can obtain the remission of temporal punishment resulting from sin for themselves and also for the souls in Purgatory.

1475 In the communion of saints, "a perennial link of charity exists between the faithful who have already reached their heavenly home, those who are expiating their sins in purgatory and those who are still pilgrims on earth. Between them there is, too, an abundant exchange of all good things." In this wonderful exchange, the holiness of one profits others, well beyond the harm that the sin of one could cause others. Thus recourse to the communion of saints lets the contrite sinner be more promptly and efficaciously purified of the punishments for sin.

1472 To understand this doctrine and practice of the Church, it is necessary to understand that sin has a double consequence. Grave sin deprives us of communion with God and therefore makes us incapable of eternal life, the privation of which is called the "eternal punishment" of sin. On the other hand every sin, even venial, entails an unhealthy attachment to creatures, which must be purified either here on earth, or after death in the state called Purgatory. This purification frees one from what is called the "temporal punishment" of sin. These two punishments must not be conceived of as a kind of vengeance inflicted by God from without, but as following from the very nature of sin. A conversion which proceeds from a fervent charity can attain the complete purification of the sinner in such a way that no punishment would remain.

The problem with purgatory is that it is the fallible wisdom of men and the Cross is totally hindered through the undivine teaching of purgatory (1 Corinthians 1:17).  To the foolish the Cross of Jesus is foolishness but to the true Christian it alone is the very power of God (1 Corinthians 1:18).  It is by the nature of man that sinners want to take part in their spiritual salvation.  It is by the sinful nature of man that sinners want to suffer for sin redemptively and contribute to the all-matchless Cross of the Lamb of God.
