The changes are interesting not only in themselves, but also because they can serve to help date a Prayer Book which has no printed date of publication; Books of Common Prayer printed since about 1860 are undated. The basic source for most of the other changes was Lynda Howell's excellent and comprehensive 1662 BCP site.
Additional information on the variations came from a number of sources, including prayer books in the author's possession, Blunt's Annotated Book of Common Prayer (1866), a report from the Convocation of York, Deviations of Modern Editions of the Prayer Book from the Text of the Sealed Books (1891), Procter & Frere's The "State Prayers" in the 1662 Book of Common Prayer appear towards the end of both Morning Prayer and Evening Prayer.
The “Our Father” is contained twice in the Bible (Matt.
6:9-13; Luke 11:2-4) with no doxology for although very ancient, it is not found in the original manuscripts.
The original, 1949, and current versions are all online.
These early writings never present it as an essential part of the “Our Father”, but rather an “embolism," (added prayer), intended to increase fervor and direct the intention of the faithful.For thine is the kingdom, and the power, and the glory, for ever and ever.
