Insisting that the celebration of the Holy Communion is historically an act of the whole church, the Rev. Basil Minchin, Vicar of Bedminster, Bristol, England, presents a most lucid and persuasive argument for a return to the practice of the early church of ""concelebration"" in which members of the congregation achieve greater participation as well as representation in the actual ritual of the Communion service. Mr. Minchin delineates clearly the evidences of the practice of worship in New Testament and Apostolic days, which emphasizes the current departure from corporate worship which was the very heart of the devotions of the early Christian Church. He is very articulate about the ways in which much that was lost may be recaptured, and he indicates the degree to which this return to lay participation is a matter of growing concern to all Christian groups, including the Roman Catholic Church. All liturgical scholars and those who care about church unity will find this study of enormous value in not only clarifying the issues but also in pointing the way toward that Christian unity to which so many seem to advance so slowly.
