Alexander Schmemann (born on this day 1921):

In essence, my body is my relationship to the world, to others; it is my life as communion and as mutual relationship. Without exception, everything in the body, in the human organism, is created for this relationship, for this communion, for this coming out of oneself. It is not an accident, of course, that love, the highest form of communion, finds its incarnation in the body; the body is that which sees, hears, feels, and thereby leads me out of the isolation of my I.
