We worship God through our questions.

Prayer is meaningless unless it is subversive, unless it seeks to overthrow and to ruin the pyramids of callousness, hatred, opportunism, falsehoods. The liturgical movement must become a revolutionary movement seeking to overthrow the forces that continue to destroy the promise, the hope, the vision.

You must build your life as if it were a work of art.

(People) can never attain fulfillment, or sense of meaning, unless it is shared, unless it pertains to other human beings.

The meaning of the Sabbath is to celebrate time rather than space. Six days a week we live under the tyranny of things of space; on the Sabbath we try to become attuned to holiness in time. It is a day on which we are called upon to share in what is eternal in time, to turn from the results of creation to the mystery of creation; from the world of creation to the creation of the world.
