A painting summons us to relish its lines and colours; a tree invites us to marvel at its roots and leafy shadows; the body of a lover beckons us to draw delight from its hidden wells; young children demand that we face them while they play, so that the miracle of their difference will not be without witnesses. Left to ourselves we shrink inwards, anaesthetised by a drowsy solipsism. Joy is waking to reality; joy is salvation from the self. It is our startled response to the call of another.
Raw materials for a Christian ethics of joy: the distance of prayer; the patience of reading; the veneration of the meal; the delight of friendship; the tenderness of eros; the love of childhood; the obedience of learning; the speed of imagining; the superfluity of art; and the omneity of language.
