We can see the way to cleanness of heart…if we look at the Church’s liturgy, for indeed if its first and supreme purpose is to give worship to God, it has the additional purpose of cleansing the mind, heart, and the whole personality.  We should see that its purpose is to cleanse the personality so that then we may be able to offer God a more adequate sharing in the worship of Christ.  The liturgy is art; but its essential material is man himself.  The various arts of man, all the creatures of the earth, the sun, the moon, and stars are brought into the act of worship.  However it is first and foremost, the total man (in Christ) who is self-offered, the total man who is articulated, the total man who is cleansed, who expresses the most powerful manifestation of worship. –Father Gerald Vann ‘The Divine Pity’
