The use of bells for liturgical purposes is an ancient one that dates from as early as the fifth century. It has been customary for centuries to use bells to call the faithful to worship or to announce other events. Such ringi11g may include the "passing bell" when a parishioner dies, or the daily ringing of the Angelus at noon_
The use of bells during the celebration of the Eucharist is also an old custom. The Sanctus bells are rung during the singing or recitation of the Sanctus (Holy, Holy, Holy, Lord God of Hosts). The sacring bells are rung during the elevation of the Host and the cup during the Eucharistic canon. At the Church of the Holy Communion, as well as most churches, the Sanctus bells and the sacring bells are one in the same set of bells.
The bells mark both reverent and joyful periods of our liturgy. For example, the bells are rung constantly during the singing of the Gloria in the liturgy of Maundy Thursday. The organ then falls silent (technically) until the first Mass of Easter at the Vigil. Practically however the organ is used sparingly. One example is the music for the sacred procession to the altar of repose on Maundy Thursday
