Servers assist the clergy in celebrating the Sacred Liturgy, especially the sacrifice of the Holy Mass. The various tasks of altar servers include leading liturgical processions, assisting with the Missal and the Book of Prayers, helping set the altar during the Mass and attending to sacred vessels after communion. Altar servers also help with the candles, incense, and processional cross. This is also a wonderful way for the lay faithful to advance in spiritual life that is centered on the Eucharist and to grow in vocational awareness. Servers participate in the Sacred Liturgy with their own work that contributes to the Work of the Faithful and the prayer of the Church and thus their service help build up the Body of Christ. In this way, altar serving is a serious ministry that requires commitment, reliability, and a certain amount of dedicated time, so it is carried out worthily.
