And here is your so called purgatorial cleansing:
2Co 5:10 For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad.
1Co 3:12 Now if any man build upon this foundation gold, silver, precious stones, wood, hay, stubble;
1Co 3:13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
1Co 3:14 If any man's work abide which he hath built thereupon, he shall receive a reward.
1Co 3:15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
None of us are perfect at death...
We will appear before the judgment seat of Jesus immediately when we die...The record of all of our works will be thrown into a fire...When the fire dies down Jesus pulls out the works that survived the fire...Only the record of the good works survived, the bad works are turned to ashes...
All those things we thought were good and were burned will become a loss, waste of time...AND, they can hinder us from receiving rewards in heaven...And since all the bad works were consumed in the fire, the fire saved us...NOW we can go into God's presence...This judgment is immediate upon death...There is no purgatory...There is no punishment...Jesus abolished the penalty of sin when he died...
Your 'learned experts' tell you that YOU are going to burn in purgatory, feel the flames as punishment for your sins...And they use this scripture to falsely convince you of that...All you have to do is read it for yourself to understand it...
