The liturgy is cosmic art. The reality revealed is the answer to the age-old dreams of the universe, of that creation which is in travail even till now; and again it is both a response and an offering and a cleansing, for this returning of the universe to the Life is itself a renewal of life, a healing and sanctifying and blessing. So, if you learn through the church’s liturgy to be clean of heart, you do three things: you achieve a personal integrity through a worship which is neither rational nor emotional but total, and therefore a total renewal of the self; you recover something of the integrity of the self in the cosmic family and share in some degree in the bringing back of the cosmos to its source; you respond to that divine power which will give you the essential integrity without which nothing else is of importance: the integrity of the self in the infinity of God.
