Liturgy (from laos meaning “faithful/religious people” and ergon meaning “actions, rituals, work or tasks”) describes the formula of purposeful religious worship.

In a Christian and Jewish sense, the term Liturgy means the complete set of formal and official rites and services of the Universal Ecclesia of Christ. The term is also used as a permitted dignity of Customary and Traditional Christian Rites that have bound themselves in unity to the one true apostolic Universal Ecclesia of Christ.

Ucadia Books Company is honoured to present Missale Christus in three parts – the most significant revelation of Liturgy since the beginning of Christianity itself.
