From Dom Helder Camara (February 7, 1909 – August 27, 1999), Catholic archbishop of Recife, Brazil:

We must have no illusions.  We shall not walk on roses, people will not throng to hear us and applaud, and we shall not always be aware of divine protection. If we are to be pilgrims for justice and peace, we must expect the desert.

Dom Helder Camara: ¡Presente!
