I Tim. 3:5 — For if a man know not how to rule his own house, how shall he take care of the church of God?
I don’t believe a man has to be married to know how to rule his own house. Ruling your own house can relate to many things other than just marriage.
Additionally, some of the disciples Jesus chose were single. Therefore, I am okay with it.
Sorry, but that's ridiculous. Your house is your family, and further v. 5 SPECIFICALLY links this to the raising of children. Given what the Scripture actually says, what exactly is that you imagine these "other things" might be?
Additionally, some of the disciples Jesus chose were single. Therefore, I am okay with it.
Which ones, and how do you know they were single? The only disciple for whose marital status we're actually told is Peter - and he was married. Anything beyond that is just unsubstantiated speculation - a flimsy basis on which to build any doctrine.
