Steve DeWitt writes a really interesting article on being a single pastor for more than 18 years. Here are a few quotes:
"... today’s bias against single pastors betrays an eschatological weakness... I think our ecclesiology could use a little eschatology. The resurrection will change our thinking in many ways. Human identity as married or single is most certainly one of them."
"... the early church was dominated by apparently single men (at least when the manuscripts were written): John the Baptist, Paul, Luke, Silas, Barnabas, Timothy, and Titus. When this list is combined with a single Savior, we should at least be in a position of neutrality on the matter."
"It is important to note that the pastoral qualifications in 1 Timothy 3 were written by a single apostle (perhaps a widow or even a divorcee but nevertheless single)... Further, we have no indication that Timothy and Titus were married. Yet they are charged with identifying and laying hands on elders who would serve under their leadership. It seems that what is good for the apostolic goose should be good enough for the pastoral gander."
