The Psalm which is sung while the Clergy are entering the Sanctuary for the celebration of the Holy Communion. Its literal meaning is The Entrance. Formerly the Introit was appointed for every celebration of the Holy Communion as well as Collect, Epistle and Gospel. In the first Prayer Book of Edward VI, the Introits were all printed before the Collect. Some of these are selected with a "striking appropriateness to the days for which they are appointed and show a deep appreciation of the prophetic sense of Holy Scripture." They are not often used at the present time as Hymns have been generally substituted, since the omission of the Introits from the Prayer Book.
