May the strength of God pilot us.
May the power of God preserve us.
May the wisdom of God instruct us.
May the hand of God protect us.
May the way of God direct us.
May the shield of God defend us.
May the host of God guard us
against the snares of evil
and the temptations of the world.
May Christ be with us.
Christ before us.
Christ in us.
Christ over us.
May your salvation, O Lord,
be always ours
this day and forever more.

Prayers from the Ancient Celtic Church is a collection of prayers from the time of Patrick (d. ca. 460-493) to the Synod of Whitby (664), and also from the Celtic Christian tradition that remained after Whitby. A few of the prayers in this book may be familiar from their appearance in other prayer books. Some may be appearing in English for the first time. All prayers (with one exception) are rendered or revised into contemporary English with the hopes that they will be useful in private and corporate worship. Includes prayers from The Antiphonary of Bangor, The Lorrha-Stowe Missal, The Book of Cerne, The Book of Dimma, St. Patrick, St. Columba and many other sources.
