Youth Ministry Ethics Question

[LifeGuide]

Here is the scenario. A 30 year old volunteer on the youth team falls into an inappropriate consensual relationship with a 19 yr. old college student in your student ministry that lasts approx a year and a half. According to state law, even though the relationship was consensual and the youth was of legal age, the 30 yr. old has abused their authority and committed sexual battery. The legal age thing does not apply. No remorse from the 30 yr. old. The first obvious step was to remove this person from their leadership role. But now, they are upset that they are to stay away from all things YM. They left the church somewhat dramatically 6 months ago. Many in the congregation are unaware of the gravity of their departure. And now they have shown back up, wanting to attend YM events. I believe that Grace and forgiveness have been extended. That being said, this is a line you cannot cross. The wound has been re-opened and the best scenario for everyone involved is for this individual to move on. Your comments and counsel are much appreciated.
