The Anglican congregation I used to be part of used the 1928 American BCP, and for private devotions I said Morning & Evening prayer out of that book:
Forms of Prayer to be used in Families (via Society of Archbishop Justus)
There is nothing in these prayers offensive to faith or morals; on the contrary, they are quite “Catholic” in flavor.
In the BCP generally, there *are *things offensive to faith (e.g. the substitution of Protestant rites for the sacraments; the Thirty-Nine Articles of Religion, and other Protestant omissions and substitutions); but there’s nothing wrong with Morning and Evening Prayer in themselves, especially as a private devotion.
When I became Catholic, my priest said it was fine to use these for my own private devotion, and for awhile I did. Eventually, however, I switched over to the Liturgy of the Hours, because it is the official prayer of the Church.
