The ministry of Altar Server is of great value to the Liturgy of the Eucharist. By ministering to the sacred vessels and the altar of the Lord, the Server allows the celebrating priest to remain focused on leading the community in the prayer of the Mass. The Server also provides a visible reminder that the entire Church is involved in offering the sacrifice of the altar. The Church teaches that the Mass is “a foretaste of the liturgy in Heaven,” and the Server demonstrates this by being a counterpart to the host of angels that attend to the Heavenly banquet.
