Responsive Service.--The glory of the Episcopal Church is its _responsive service_, as provided by the Book of Common Prayer. By means of this, the people have their part in the service. Thus {230} worship becomes general throughout the whole congregation and the people are not silent spectators, nor yet simply an audience. But however reasonable and desirable this may be, there is a deeper principle involved. The responsive character of the services brings out and emphasizes the "Priesthood of the People." St. Peter, in his First General Epistle, writing to the Baptized, says of them, "But ye are a chosen generation, a royal Priesthood, an holy nation, a peculiar people, that ye should show forth the praise of Him who hath called you out of darkness into His marvelous Light." Thus the Baptized are called in Holy Scripture "a royal priesthood," and this doctrine pervades the Prayer-book. The whole system of responsive worship is founded upon the Priesthood of the Laity, and enables them to _show forth the praise_ of Him who hath called them out of darkness into His marvelous Light. (See AMEN; FORMS; also VERSICLES.) Retable.--A shelf at the back of the Altar, usually fastened to the reredos, on which are placed the Altar cross, the vases for flowers, and the candlesticks. The necessity for the retable arises from the fact of the reverent usage of the Church, which requires that nothing shall be placed on the Altar but the Eucharistic vessels, the book rest and the book. Retreat.--This is a term used to designate a time of retirement as a means of deepening the Spiritual life of the Clergy, for whose benefit it is held. It involves a temporary submission to the monastic rule of silence, meditation, confession and conference. In Holy Scripture we read of our Lord and His disciples {231} constantly going into retreat in some shape or other. Christ on the hilltop, St. Paul in the desert near Damascus, St. Peter on the roof of his house, retired for prayer and meditation. The Retreat as now conducted gives each one the opportunity to make special effort to see more clearly those great principles of Religion which can only be seen by such effort and by such special spiritual exercises. In some Dioceses an annual Pre-Lenten Retreat is held for both Bishop and clergy in preparation for the solemn and spiritual work of Lent. It is a cheering sign of spiritual revival which many will welcome, to see Bishop and Clergy thus meeting and withdrawing for a season from the world, for prayer, for intercommunion and instruction.
