This volume has services for the days of the week, important days on the liturgical calendar, and for the honoring of various Celtic saints. The services include times for singing (and occasional suggestions for the song/hymn) but does not include the text or music of any songs. Most of the prayers are original but some prayers are drawn from the Carmina Gadelica and other traditional prayers. While this may be used for private worship, it is designed for public worship and so sufficient copies should be bought. This would be the best arrangement for a stable group that is going to make continued use of the services. An alternative is to buy this volume and then purchase the CD containing pretty much the same text, which can be modified and specific services printed for public worship events... However, you would still want to have this in book form for easy reference and sense of layout.
This book is an excellent resource for those interested in Celtic Christianity and seeking a framework for their personal or corporate worship and devotions. Ray Simpson is Guardian of the Community of Aidan and Hilda, as well as the founder of the Lindisfarne Mustard Seed Project. He is thus well-qualified to write on this subject and this book is evident testimony to this. Read it and use it!
