[Topic] Worship and Liturgy [Orthodox] The 'Divine Liturgy' is the centre of Orthodox spirituality. Worship is usually in the vernacular, though Greek is also used. [Roman Catholic] Worship is centred around the Mass. Following the Vatican II council (1962-5), greater emphasis was placed on worship in the vernacular, though the traditional Latin ('Tridentine') Mass is also used. [Protestant] 
There are a wide variety of worship styles. Examples include the spontaneity of the Pentecostal churches, and the more traditional worship of the Anglican churches in the Catholic tradition.
