Why are we called to active participation? The basic element of liturgy is prayer. Indeed, prayer is the means and the ends of liturgy. The Orthodox Fathers teach that prayer is the art of arts and the science of sciences. Anyone who has studied either art or science knows the importance of practice.
Science is the study of natural phenomena through both theory and practice. Therefore the laboratory is indispensable. The same can be said for art. An artist dose not simply study art, but practices it, and produces art. The artist’s studio is essential. In the same way the Church’s liturgy is the laboratory and studio of prayer to which all Christians are called.
