It is derived from two Greek words "lios" means "people" and "ergon" means "work." The original Greek word was used to express a public work of any kind, not only religious, but by the time of the Septuagint it had come to be applied particularly to the services of the Temple.
Now the word is used for all church worship, especially the Eucharist as the chief act of public worship.
The main church liturgies are:
Eucharist liturgy (Holy Mass).
Baptismal Liturgy.
Marriage liturgy (Matrimony).
Blessing of the water.
Ordinance of bishops, priests, and deacons.
Consecration of the churches.
