An overseer must not give people a reason to criticize him, and he must have only one wife. He must be self-controlled, wise, respected by others, ready to welcome guests, and able to teach.
But do not put younger widows on that list. After they give themselves to Christ, they are pulled away from him by their physical desires, and then they want to marry again.
If any woman who is a believer has widows in her family, she should care for them herself. The church should not have to care for them. Then it will be able to take care of those who are truly widows.
