The very first item I checked in the new Customary was the Office for St. Columba, my patron. The Collect from that office follows.
ALMIGHTY God, who didst fill the heart of Columba with the joy of the Holy Spirit, and with deep love for those in his care: grant to thy pilgrim people grace to follow him, strong in faith, sustained by hope, and made one in the love that binds us to thee; Through Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, one God, for ever and ever.
I can’t say that I’m too fond of the composition. It’s hardly an improvement on the Collect from the 1929 Scottish Book of Common Prayer. I would have wished a prayer that invoked St. Columba’s intercession.
