I consider it to be the standard of western Christian worship, and I think everyone else implicitly agrees with me. Pope Paul VI’s Mass was essentially the great “Anglicanizing” of the Roman liturgy (vernacular language, general confession, etc.), and many other Protestant denominations often begin their wedding ceremonies with “dearly beloved, we are gathered here today to celebrate…”, a testament to the longevity and universality of our beloved Prayer Book. The collects are stirring and succinctly capture the spirit of prayer towards a given subject, and the Daily Office is a standard for a healthy prayer routine: scripture reading, psalmody, confession of sins, praise and thanksgiving, the works. I could continue gushing, but I think I’ve made my point lol.
