A Deacon is not required to have a wife.
"Let the deacons be the husbands of one wife" is simply a directive against polygamy. It doesn't mean they MUST be married. Just that it isn't suitable for Christian leaders to have multiple wives.
I se that a litle differently. I would offer first the office is not without children so that the duel ministry of the husband and wife as one, has some experience
and success when consoling couples or singles that are having relationship issue.
One wife is the requirement. A divorced husband would not be qualified in keeping the ceremonial office .And neither a single woman nor man. If a man cannot control his own nature he was not allowed to Sheppard a flock. It does not mean that cannot be used in other ministries.
If it applied to Presidents one would have been impeached a few years ago rather than lowering the moral decline with a new poster child.
It is in the context that a woman should be silent in the church setting and not council with men that are not their husbands in order to keep down on sexual immortality, now that woman was not literally separated from men at church and eyes focus on the wrong things, seeing the only glory to be seen is the veiled glory of faith, not the temporal representative glory of man or woman.
And let these also first be proved; then let them use the office of a deacon, being found blameless. 1Ti 3:10
Interestingly in the description of a deacon right from the start it is them… giving the first responsibility of that office to a wife as the stablelizer .
Even so must their wives be grave, not slanderers, sober, faithful in all things.Let the deacons be the husbands of one wife, ruling their children and their own houses well. 1Ti 3:11-12
It shows the reward of faith, the increase of it.
For they that have used the office of a deacon well purchase to themselves a good degree, and great boldness in the faith which is in Christ Jesus. 1Ti 3:13
The teaching again is in respect to the dynamic duel. With children required
Titus 1:6 if any man is blameless, the husband of one wife, having children that believe, who are not accused of riot or unruly.
No wife, no children, no Job.
