If we have been called to unity, the way to God, for us, passes through our neighbor. It is through this passage, which may sometimes be as dim and dark as a tunnel, that one comes to the light. This is the mysterious path God invites us to take. Each day there are opportunities to perfect this art, a tiring one at times and exhausting, but always wonderful too, vital and fertile, the art of "making ourselves one" with other people: the art of loving.
