St. Paul did not state that "we are holy without blemish and unreprovable before Him in the present tense." The ASV states "And you, being in time past alienated and enemies in your mind in your evil works, yet now hath he reconciled in the body of his flesh through death, to present you holy and without blemish and unreproveable before him if so be that ye continue in the faith, grounded and stedfast, and not moved away from the hope of the gospel which ye heard, which was preached in all creation under heaven".
Notice the word "if" in the text. The word "if" indicates that the phrase that precedes it is a conditional phrase. That is, "to present you holy and without blemish and unreproveable before him" is a conditional phrase. The condition on which our Lord will present you holy and blameless is if "ye continue in the faith, grounded and stedfast, and not moved away from the hope of the gospel which ye heard, which was preached in all creation under heaven".
The text says nothing about people being holy and blameless before God at a present point in time. If tomorrow you renounce God, become an atheist, and gleefully go out raping and killing people until your death, do you think that Jesus will "present you holy and without blemish and unreproveable before him"? No. Of course not. Our Lord will "present you holy and without blemish and unreproveable before him" at some future point in time after "ye continue in the faith, grounded and stedfast, and not moved away from the hope of the gospel which ye heard, which was preached in all creation under heaven".
That future point in time may be immediately upon your death, or after purgatory, should you end up in purgatory.
Again, there is nothing in Scripture that you are going to be able to produce here that refutes or is inconsistent with the Catholic doctrine of purgatory. Protestants have been attempting to do so for 500 years, and to no avail. What makes you think that post number #276 on Christian Forums will be the watershed moment that finally disproves the Catholic faith? Do you really think that you are going to be able to produce a verse from Scripture that disproves purgatory, when we have have thousands of intelligent priests, theologians, lay apologists among our ranks, who have already considered every verse of Scripture and argument that you will make a thousand times? Even if you come up with some novel argument that I have difficulty answering here, all I need to do is simply refer back to one of those thousands of people in the history of the Church, who has already considered your argument and has a powerful refutation of it.
You will debate on endlessly here, and you will never prove that Scripture contradicts the Catholic doctrine of purgatory. There are literally hundreds of pages from threads on this site where people have attempted to do so, and failed.
Colossians 1:22 does not state that "all sin is removed". Colossians 1:22 (ASV) is cited above. As for your question, that information has been provided numerous times on this forum. I suggest that you use the search feature, which is quite useful. You can also find the information at Catholic Answers, or at numerous other places on the internet, using Google.
