The Golden Rule

The golden rule is part of every religion, so it qualifies as one of the single, unifying theme of all faiths.  In alphabetical order:

 

Buddhism: "In five ways should a clasnman minister to his friends and families; by generosity, courtesy, and benevolence, by treating them as he treats himself, and by being as good as his word."

 

Christianity: "Do unto others as you would have them do unto you."

 

Confucianism: "What you do not want done to yourself, do not do to others."

 

Hinduism: "Men gifted with intelligence...should always treat others as they themselves wish to be treated."

 

Islam: "No one of you is a believer until he loves for his brother what he loves for himself."

 

Judaism: "Thou shalt love thy neighbor as thyself."

 

Taoism: "regard your neighbor's gain as your own gain, and regard your neighbor's loss as your own loss."
