<div><p>What is worship? Keith F. Pecklers, SJ, answers this important theological question by focusing on the basics of Christian worship. Beginning with the definitions of such terms as ritual&quot; and *liturgy - he writes in a very readable style about the historical/theological foundations of worship, tracing the evolution of Christian liturgy from the earliest centuries of the Christian era up to the reforms of Vatican II.</p><p>Pecklers focuses on such liturgical issues of importance in our post-Vatican II Church as: inculturation, popular religion, and the social responsibility that authentic worship requires. He also considers some key social issues of the twenty-first century and their impact on our worship: the break-up of the stale parish community and decline in church attendance; the clergy shortage and priestless parishes; ecumenical liturgical cooperation and interreligious dialogue; the credibility of preaching; and how worship welcomes or excludes the marginated.</p><p>Chapters are *Worship and Ritual, - *Worship in Development and Decline, - *Worship in Crisis and Challenge, - *Worship in Transition, - *Worship and Culture, - *Worship and Popular Religion, - *Worship and Society, - and *Worship and the Future of Christianity. -</p><p><i>Keith F.
