Catholicity of Prayer III
It is in the liturgies it provides for the sacraments that the Prayer Book’s claim to be fully reformed and fully catholic – without being puritan or papist – is most contested. Naturally, the chief focus is on the service known variously as the Mass, the Lord’s Supper, the Holy Communion, or the Eucharist – all of them terms with ancient origins, and varied patterns of use among catholics and protestants.
