I find your words support this idea:
Some added to the church will be gold, some silver, some precious gems who will inherit heaven and be counted as reward to the minister who served them and some will be such that they are lost in the fire of judgment on “the Day”. The minister will still be saved, but the loss of church members will be a bitter loss, like on who has escaped from a fire with nothing
What is it that makes someone - a brick - in the Corinthian Church, or Chloe’s Church in the Corinthian Church, or a family in Chloe’s Church - gold, silver or precious gems? It is, as Paul says, their works, or rather, do they let Christ work through them. Therefore, each member of the Church - at all levels - has a responsibility to build on the foundation of Christ with gold, silver and precious gems - good works.
As regards to the loss issue, I don’t think your idea squares with Christ’s parable of the Sower and the Seeds. Yes, there are some things a priest can control, like preaching and practicing orthodoxy. But each believer, ultimately, bears individual responsibility, and a priest cannot be held responsible for each person’s ultimate end.
In 16-17 Paul is letting the church members know that pursuing a course of division will cause them to be judged and lost.
16 Do you not know that you are a temple of God and that the Spirit of God dwells in you?
17 If any man destroys the temple of God, God will destroy him, for the temple of God is holy, and that is what you are.
If I accept your argument of exclusive language from vv9-15, Paul gives no indication of a return to inclusive language in vv16-17. In your argument, the
"you" in v16 still refers to Paul and Apollos and ministers.
I agree with your thoughts on our imperfect attempts to serve God, but if the passage is referring to people being lost in the fire of judgment on “the Day”, that isn’t purgatory and the lack of purification language makes sense. So it becomes a question of whether or not one can dismiss Paul’s interpretation given in verse 9 and replace it with an interpretation that is more amenable to a purgatorial interpretation of the passage. For the reasons listed above and elsewhere I don’t believe that is possible.
Notice in vv13-15 Paul makes no mention of damnation, which would equate to your idea of “people being lost in the fire of judgment on ‘the Day’.” All he speaks of are those who will be saved:
14 If any man’s work which he has built on it remains, ***he will receive a reward.***15 If any man’s work is burned up, he will suffer loss;
but he himself will be saved, yet so as through fire.
This is very clear language to a process where our building is tested and either found nearly pure or not so nearly pure, and of people being purified of their wood/straw/hay works to enter heaven pure.
Again, there is no - can be no - separation of man and his works, else Christ’s telling of the sheep and the goats in Mt 25 makes no sense.
It comes down to that I do not agree with your interpretation of Paul in 1 Cor 3.
