Liturgy is the compilation of rites and ceremonies concerning the divine offices of the Christian churches. It's a word that applies more to masses or rituals gives Catholic church.
The word comes from the Greek readers, a word used to describe someone who performed public service or led a sacred ceremony.
Although the word liturgy was used in antiquity, it was only after the 8th and 9th centuries that it came to be used in the context of the Eucharist in the Greek Church. The term became part of the Catholic Church much later, around the 16th century.
The central manifestation of the liturgy is the celebration of the mystery of the death and resurrection of Jesus Christ and the worship of God.
Initially the liturgy was the responsibility of the apostles and bishops, but it is known that some churches created their own liturgy, such as the Church of Alexandria in Egypt and Antioch in Syria.
Until the middle of the 16th century there was no general and mandatory rule for the liturgy, but it was implemented by Pius V and Clement VIII. The Second Vatican Council meant a renewal of the liturgy, giving greater emphasis to Sacred Scripture in the liturgy of the word, including the use of other languages instead of Latin, so that more people could participate more active.
The Lutheran liturgy derived from the rites of the Catholic Mass, and adopted forms of prayer and singing. The Calvinist Church, for example, simplified the liturgy, but the Anglican one kept almost all the liturgical traditions of the Catholic Church.
There are several manifestations of liturgy, such as the Ambrosian Liturgy, Liturgy of St. John Chrysostom, Mozarabic liturgy, oriental liturgies.
there is the liturgy of the hours, this name being the designation of readings for different times of the day, with hymns and biblical passages. There is also the commented liturgy, with explanatory texts about the liturgy in question.
