Liturgy, it has often been said, implies doctrine. Nowhere is this more patently clear than in the rubric before the second Exhortation ‘in case he [the Minister] shall see the people negligent to come to the Holy Communion’ in the Prayer Book of 1662. In view of the fact that ‘An Order for Holy Communion’ contained in the Report of the Liturgical Commission, April 1966, has departed from the valuable precedent of 1662, it may not be without contemporary value that we enquire into the origin, purpose and structure of this second Exhortation.
