The House of Cyril and Methodius

"Let us not underestimate how hard it is to be compassionate. Compassion is hard because it requires the inner disposition to go with others to place where they are weak, vulnerable, lonely, and broken. But this is not our spontaneous response to suffering. What we desire most is to do away with suffering by fleeing from it or finding a quick cure for it."
— Henri J.M. Nouwen

Loving someone, showing compassion, is recognizing that we are one. We are not simply a part of one body, we are one body.
