I love the message of this mock poster. Often those who espouse to believe in "unity" deny that belief by the way that they behave. I think that religious folks can sometimes be the biggest transgressors in this area.. not that I have any first hand knowledge.
Here are a few things that wise people have said on the topic along with my strange and pithy commentary.
"United we stand; divided we fall." -Aesop
[Gotta love the simplicity. I think the heart of unity is all about finding common ground to unite around.]
"The unity of freedom has never relied on uniformity of opinion." -John Fitzgerald Kennedy
[I am glad that unity is not based on my opinions because they change so much.]
"Unity to be real must stand the severest strain without breaking." -Mahatma Gandhi
[Commitment will always be tested. Anyone who has been married for any length of time understands this.]
"I know that my unity with all people cannot be destroyed by national boundaries and government orders." -Leo Nikolaevich Tolstoy
[The things that unify us are greater than the things that divide us. Focusing on other things create division and strife.]
"I dream of the realization of the unity of Africa, whereby its leaders combine in their efforts to solve the problems of this continent." -Nelson Mandela
[Solving problems can unify opponents like nothing else when the focus is on solutions and not problems.]
"The moment we break faith with one another, the sea engulfs us and the light goes out." -James Baldwin
[The words "break faith" speak to me about why unity is often so hard.]
"We have learned to fly the air like birds and swim the sea like fish, but we have not learned the simple art of living together as brothers." -Martin Luther King, Jr.
[Unity is an art that can only be learned when we acknowledge another as a brother or sister.]
