Embroidered and zippered covers are made of vinyl and fits Liturgy of the Hours and the Book of Christian Prayer. Zippers begin at the top and end prior to the ribbons to preserve them.
Obedience unites us so closely to God that it in a way transforms us into Him, so that we have no other will but His.
If obedience is lacking, even prayer cannot be pleasing to God.
— Saint Thomas Aquinas
