worship well that they may live well;[21] the proposition that has been made here is that men must live well if they would worship well. It makes little difference which way the thought is expressed, the mode of expression depending on the part of the circle at which we begin our course. Life runs up into worship and worship runs out into life. Each leads into the other. The use of a liturgy is an added power to public worship. It is only by liturgical aids that public worship can become common worship. A liturgy delivers a congregation from the spiritual idiosyncrasies of a minister as well as disciplining those of the worshippers themselves. The comprehensiveness and symmetry, the saneness and dignity of the Book of Common Prayer are educative forces of enormous value. Left to themselves men lose the true perspective of things; they dwell too much on matters of secondary importance, and become insular in their outlook. A liturgy comes in as a corrective of these constitutional failings; it confronts us with all that is vast in the realm of truth; it calls us away from the consideration of those things over which we have pondered until morbidness has seized upon us; it ministers that grateful rest which comes from the mind being freed from the contemplation of one set of interests, by being caught away by and absorbed in new and wider interests; it rounds out the devotional life; it invites us to lean upon the prayers of others as we desire them to lean on ours. All who aspire to worship well in the congregation must note that the liturgy sets the tone for all devotions. Those who in private affect spiritual exercises foreign to the character of the Prayer Book of the Church, may get a certain emotional satisfaction for the moment, but they purchase the luxury at the cost of weakening their power for common worship. Their private prayers form no preparation for their public prayers. The clergy have it as a grave responsibility to see that the books of private devotion which they put into the hands of their people are such as fit into the Church's system.
