How interesting indeed!
As much as I fully understand that the hard core cessationist worldview compels its adherents to regularly deny what should be obvious to everyone, I am still a bit surprised that you have failed to recognise that the context of what Paul is saying is set within the assembly of the Saints, or as we would say, the local Church meeting.
Even though Paul is establishing some correctives for the Church when it comes to the ministry of the Holy Spirit within chapters 12, 13 & 14, his admonitions begin back in chapter 11 where in verse 17 and 18 he says;
(1Co 11:17-18 NIV) In the following directives I have no praise for you, for your meetings do more harm than good. In the first place, I hear that when you come together as a church, there are divisions among you, and to some extent I believe it.
In 11:20 he begins to address the problem of the abuse of the Lord’s Supper, where Paul makes reference to “when you come together”. Now you are more than free to broaden Paul’s use of
ekklesia to more than just the corporate (weekly?) collection of the Saints to say a home group or to a prayer meeting, but to try and say that he is speaking about the worldwide Body of Christ (or similar) makes absolutely no sense, nor should it even make any sense for the cessationist.
When it comes to his correctives regarding the Lord’s Supper, he finishes off in verses 33 & 34 by saying that “when you gather to eat, you should all eat together”, where he ends by instructing us that if “Anyone who is hungry should eat at home”; so we have a reference to the corporate meeting and to our domestic households.
With chapter 12:1 Paul is still speaking of the corporate assembly of the Saints where he moves away from the abuse of the Lords Supper with a new subject which he begins with Περὶ δὲ τῶν πνευματικῶν ἀδελφοι or “Now about spiritual matters brothers . . .”
As I've said before, the best approach for defending the cessationist worldview is to remain quiet, where the cessationist can maybe hope that if they do not speak about spiritual matters that they might be able to maintain the status-quo that has been built around their particular tradition; but of course this does go against Paul's declaration in 1Cor 12:1 "Now brothers I do not want you to be ignorant".
Of course, if you still want to believe that Paul is not speaking to the assemblies of the Saints, then you may be able to promote the view that when Paul says in 14:27-29 that there are to be only three prophecies and three tongues where each tongue is to be subsequently interpreted, then you might be able to say that Paul only ever expected to see tongues spoken on three occassions before they were stopped; maybe you should give Johnny Mac a call to see what he could do with this (or maybe not do with it).
