The article can be listened to from jw.org. There is more than one question. The first is about rebaptism. This post is in regards to the second question.
The second question talks about living arrangements, and states that it would not be wise for several people to share a house where two members of the opposite sex would would not normally be alone, because others would normally be there, but it could momentarily happen if others were away. I got to thinking what about the missionary homes that are shared by several missionary couples?
Couldn't there be times when momentarily one spouse could be at the house and another missionary of the opposite sex could be there? What if the missionary husband who was an elder had a congregation matter to attend to, and another brothers wife was out on a bible study with a different person in the congregation. Taht could leave the sister of the first elder and the husband of the other wife mentioned home alone...
