No, what Paul is saying is that being single is ideal since it allows one to concentrate on working for the Lord without worldy distractions.
That view is not only for the leadership but for all Christians.
Paul, however, makes it clear that if one cannot handle being alone, then one should marry.
As for remarriage, there is nothing against remarriage, Moses was remarried.
The verse means to be the husband of one wife, one at a time, not that if your wife dies you cannot remarry.
These are simply man-made traditions (Mk.7:7)
Indeed; so is the call to accept tonsure, go into priesthood, or marry.
not that if your wife dies you cannot remarry
The Church's interpretation East and West is that a priest cannot either marry or remarry, but he can stay married and enter priesthood in some limited circumstances. The notion that the "husband of one wife" allows remarriage is your spin, and I prefer to stick with the traditional interpretation we've had for at least since the 4th century.
Why is this interest among Protestants in the disciplines of the Church, anyway? I thought you ran off because you did not like Church disciplines; want to play priest now?
