While there is a common core to historic Western Christian liturgy, there is also considerable diversity. Rites differed from region to region and from place to place. Regional improvisations on the basic framework of the liturgy led eventually to a proliferation of liturgical books in the Western church, with many variations even within the same regional traditions.
The Coptic and Ethiopian liturgies are textually similar but quite different in style and setting. The Coptic liturgy is sober and restrained, while the Ethiopian liturgy is full of life and exuberance.
