Venerable Fulton Sheen
“The marital act is nothing but a fragile and shadowy image of Communion in which, after having offered ourselves under the appearance of bread and wine and having died to our lower self, we now begin to enjoy that ecstatic union with Christ in Holy Communion-a oneness which is, in the language of Thompson, ‘a passionless passion, a wild tranquility.’ This is the moment when the hungry heart communes with the Bread of Life.”
