The Golden Rule in many faiths

When Introducing scouts to the idea of an Interfaith service, it can be very tricky for them to understand. Most have only grown up with a single faith, and may not be as exposed to the faiths of others. One brief example to give them is the Golden Rule. There are many ways to express it, and most of the world's religions contain that sentiment in some form or fashion. (Thanks to MacScouter.org for the list)

Blessed are those who prefer others before themselves. -- Baha'i Faith

Hurt not others in ways that you would you yourself would find hurtful. -- Buddhism

Do unto others as you would have them do unto you. --Christianity

This is the sum of all duty: treat others as you yourself would be treated. -- Hinduism

No, it doesn't mean that all religions are interchangeable or that it doesn't matter which you follow... But we do have some commonalities among them.
