The last point of the Scout law is Reverent.  Below are some ideas for Scout's Own or services for Scout Sunday. 

The Boy Scouts of America designates the Sunday that falls before February 8 (Scouting Anniversary Day) as Scout Sunday, which is the primary date to recognize the contributions of young people and adults to Scouting. However, each chartered organization can use either of two other options to celebrate this special day.

An organization can adopt a specific Sunday to celebrate. In the instance of the United Methodist Church, Scout Sunday is celebrated on the second Sunday in February. It also is permissible for a local church to celebrate on the Sunday most acceptable to the pastor and congregation.
