The second qualification: “Faithful spouse” (3:2)
The second qualification in the list deals with the
overseer’s married life. Careful research has shown that
this qualification means that whether one is a husband or
a wife it is important to be a “faithful spouse.” It requires
that an overseer, if married, be faithful and be “a one-spouse
kind of person.”

According to Lucien Deiss (notes to the French
Bible, the TOB, Edition Intégrale, p. 646, note a), this
Greek phrase was used in Asia Minor, on both Jewish
and pagan gravestone inscriptions, to designate a woman
or a man, who was faithful to his or her spouse in a way
characterized by “a particularly fervent conjugal love.”

When I read Deiss’ comment about how this phrase
was used on ancient grave inscriptions in Turkey, where
Paul and Timothy ministered, I confirmed it with him
myself, reaching him by telephone in Vaucresson, France.
Some might find this insight into 1 Timothy 3:2
surprising because modern versions of the Bible
translate this Greek phrase as – “husband of one wife” –
making this qualification appear to be restricted to men
only! Instead, rightly understood, this qualification is
about faithfulness in marriage by a Christian spouse. It is
not saying that oversight is “for men only.”

This is also in his book “Familiar “Leadership” Heresies Uncovered” which is very insightful, altho the title is a mouthful.

The Keever citation is a typo, it is Craig Keener, but when I look there I cannot find it. So I would use the above ref.
