It's just wondering aloud about ALL the gifts possibly ending...miraculous and ministerial alike...upon the completion of the revelation given to Paul. Might help explain the shift from pastors, etc, being a defined spiritual gift to "if any man DESIRES the office," he doesn't need to show he has the gift but, instead, has to meet certain requirements. Makes me wonder if a discontinuance of all the gifts would help explain the Church as a whole falling into retro-Judaized apostasy within 100 years of Paul's homegoing (which Paul foretold would happen, discontinued gifts or no).
But like I said all along...I dunno. Just wondering.
