Play is meaningful action that does not need to seek its meaning in some achievement exterior to itself. It is what we do because we do not have to. It is action to which the future opens as gift rather than as burden. The life of the Trinity is sheer play. As play with the Trinity, liturgy is anticipation of life in the Fulfillment–the closest we get to freedom. It must be admitted that liturgy-as-play is a rather rare occurrence in America’s recognized churches.
