Liturgy," derived from the classic Greek words "Liaw" meaning "People" and "Ergia" signifying "work," traditionally refers to a public service carried out for the people. This term has been in use since the era of the Apostles to represent all officially organized worship activities by the Church, intended to be offered by all her members or on their behalf. Over time, however, "liturgy" has evolved to predominantly denote the service of the Eucharist, despite its application to other religious ceremonies.
The concept of liturgy extends beyond the physical participation of believers, both clergy and laypeople, in specific religious rituals such as the Eucharistic liturgy, Vespers, Matins, Baptisms, or Marriages. In its essence, liturgy signifies an authentic communion with Christ, transcending the confines of time spent in communal worship.
This liturgical life, therefore, is not confined to the periods when a believer partakes in communal worship. Rather, it pervades the believer's life, dwelling within his heart even during solitary moments. In essence, "liturgy" embodies a mode of living that the Church encourages. Through its practice, the Church recognizes her identity, fulfills her mission, and realizes her purpose, which is to foster spiritual growth and life in Jesus Christ.
