O GOD, who by the preaching of thy blessed servant Saint St. Columba didst cause the light of the Gospel to shine in these islands: Grant, we beseech thee that, having his life and labours in remembrance, we may shew forth our thankfulness unto thee for the same by following the example of his zeal and patience; through Jesus Christ our Lord.  Amen.

– Collect for the Feast of St. Columba (9 June) from the Scottish Prayer-Book (1929).
