If you're ordained in the C of E, you already own this book. If you're about to get ordained into the C of E, you're about to own this book.
What's in it?
Well, the bits you will use the most are the Marriage service and the Funeral service.
The versions are given in full here including the alternatives: traditional language vs modern language (e.g. key difference in preface to marriage: "sexual union" vs "bodily union" in traditional language, and all that kind of thing)
They also print out likely scripture passages for funerals and weddings, which is useful.
As for the rest of the book, well, what you might not expect are quite a lot on healing services. This is useful, and practical and there's an interesting little theological introduction.
Other oddments; an order for prayer and dedication after a civil marriage and also "thanksgiving for the gift of a child" (whilst baptism is in the "Christian Initiation" book).
I wonder how many people use "order of prayer at the home for before the funeral". But it's good that it's there, I suppose.
This volume, then, is the part of the authorised book of prayer for the Church of England today, now extended over several volumes.
No doubt it was painstakingly argued over and debated at General Synod.
Whatever one thinks about it, it's indispensible to any ordained minister in the Church of England.
