You provided no basis to believe it would be a worthwhile endeavor to do so.
So you are a fervent RC who cares not to defend a core belief of your church? If there is Biblical warrant that clearly supports purgatory, I will publicly admit it and begin defending it. But if there be only conjecture taken from Scripture that does not support it, please admit that it is a man-made doctrine.
