Worship is the outcome of living faith, the expression of a sincere conviction in some external and visible form. There is innate in every society and individual the urge to communicate and share conviction. Good naturally spreads itself in companionship. The Church is a society both human and divine; divine in its origin and support and human in its composition. It gives effect to this urge in two main streams, the liturgy and private devotion. As a society its worship is found in the liturgy, but the individual members of that society express themselves in a variety of private devotions. These two streams are nevertheless vitally connected. The liturgy of its very nature and because it is the official and common worship of the body, politic remains somewhat static and is carefully prescribed ano ruled by laws.
