As for 'present distress', let's look at context. Paul died, it is thought, in the tenth or eleventh year of Nero - he is speaking, according to Poole, of a time in the near future when the church will experience serious hardship. 'Distress' would indicate persecution the likes of which 99.9% of this board have never seen, let alone experienced themselves. But, and correct me if I'm wrong, you refer to it as though he intended little more than inconvenience in these words. Roman oppression vs. "It's too much trouble/inconvenient."
I am not student of church history and I will confess to not believing it necessary to be one to understand the bible. If we look at it in context 'present' indicates to me something that was occuring at the time when Paul was writing. Looking at the book of 1 Corinthians, whatever was happening in Corinth, the christians there;
1) still had access to courts of law, since they were having lawsuits against one another (ch 6)
2) Still were able to sit down in an idol temple to eat meat (ch8-10)
3) Still could shop openly in the pagan meat-markets (ch 10)
4) maintained good enough relations with the pagans that they were from time to time invited to eat dinner together (ch 10)
5) still had enough luxury that some of them were able to turn the Lord's Supper into a drunken feast (ch 11)
In fact, in his second letter to the Corinthians, Paul while extorting them to give, describes them as being relatively rich (2 Cor 8:14) in comparison to other christians.
So while I do not know exactly what Paul was referring to when he said 'present distress' I do not believe persecution of holocaust type proportions in necessary to activate the principle.
In any case, I am not sure how the potential death of a woman in childbirth (which I believe was the context of our discussion) is considered an inconvinience.
