It is easy to forget that so much of the missionary work of the Church was done through its worship and the old Latin Mass; the people of Kent were moved by Augustine's chanting monks,
the Jesuits were rowed up South American rivers to the sound of violins, flutes and voices. Engaging the heart and senses seems to have been the first act of missionaries in the past, using beautiful music, stimulating a sense of wonder,
causing people to reflect and to be still, to recognize God as Beauty, to look for his presence in their hearts.
