You really need some extra help with cleaning your church facilities. Why not just hire a teen to vacuum a few hours a week and pay them per hour? Then you could avoid the paperwork (I-9, social security and income tax withholding, unemployment compensation etc.). Can't they just be an independent contractor so I don't have to hire them as an employee?
Most people retained to do the day-to-day work of a church are considered employees. The IRS has several factors they have identified that clarify whether a person is an independent contractor or employee. In the case of hiring a teen, he/she should not be considered an independent contractor because they fit the category of employee on several tests--they are given instructions for when, where, and how to work; paid by the hour; trained; work done on employer's premises; etc. The IRS expects the church to comply with the reporting, withholding, and payment obligations that exist when an individual is determined to be an employee.
