We don't know if St. Paul was "not allowed" to marry. It appears from his letters that he simply chose to be celibate. Like I said, the celibacy discipline was not adopted legally till the 4th century, and many Christian clergy were adult converts already married; such was St. Peter.
This being said, the Church always distinguished between St. Peter's situation,-- a married man entering priesthood (allowed in the early Church, still allowed in the East, and for converts in the West), -- and what would have been the case for St. Paul, an ordained clergy marrying (not allowed anytime and anywhere, as far as I know).
And that is exactly what, I believe, we were saying.
That there is no scriptural basis for celibacy among church leadership.
By the way, the NAS Roman Catholic Bible, has Do we not have the right to take along a Christian wife, as do the rest of the Apostles and the brothers of of the Lord and Kephas?(1Cor.9:3)
Like I always say, you can't trust those modern translations!
