The Altar Book for the BCP 2019 is presented here for trial use, to be downloaded and printed and inserted into a three-ring binder. Feedback can be emailed to firstname.lastname@example.org. The Altar Book contains a simple enlargement of the Standard BCP Liturgy, as well as a full musical supplement for a sung celebration of Holy Communion. It is recommended that you buy either page-tabs or ribbons for functionality. Twelve months will be given for refinements to be made and feedback incorporated, and then this will be published as a deluxe, calf-skin-over-board, two-color Altar Book, which will be available for sale, the Lord willing, in late Summer 2021.
