Word in Season. Use of the Bible in Liturgy. Author: Donald Gray. This latest publication of the British Joint Liturgical Group is intended as a contribution to the work currently being undertaken to explore the possibility of an international ecumenical lectionary. The JLG's own calendar and lectionary, first published in 1967 as one of its earliest pieces of work, made an important contribution to the revised service books of many churches. In this book the Group looks again at the principles involved in the ordered use of the scriptures in worship. Please Note this book is a Print on demand Publication.
