In Christian liturgy, a collect [kɒlɛkt; kol-ekt'] is both a liturgical action an a short, general prayer. In the Middle Ages, the prayer was referred to in Latin as collectio, but in the more ancient sources, as oratio. In English, and in this usage, "collect" is pronounced with the stress on the first syllable. Collects appear in the liturgy of the Mass of the Roman Catholic, Anglican, Lutheran, and some other rites. Beginning with the Lutheran Book of Worship in 1979, contemporary Lutheran liturgies have dropped the name "Collect" in favor of "Prayer of the Day", although the meaning, structure, and function remains the same.
