Keith Pecklers 
Worship [PDF ebook] 

In Worship, Keith Pecklers aims to gives theologians, liturgists, clergy and laity of all denominations a new sense of the theology of liturgy.
From a historical/theological treatment of the evolution of Christian worship in the West, Pecklers addresses 20th century liturgical reforms and emphasizes the liturgy”s role in the social and moral transformation of human society. The social dimension of worship is further highlighted in chapters on popular religion and inculturation.
He considers the future of Christian worship in light of a new sociological reality: the break up of the stable parish community, credible preaching within an increasingly secularized society, hospitality to those who are often made to feel like pariahs in our assemblies, and the growing rift between conservatives and progressives who share membership in the same church.
