O loving God, you called your servant Aidan from the peace of a cloister to re-establish the Christian mission in northern England, and endowed him with gentleness, simplicity, and strength: Grant that we, following his example, may use what you have given us for the relief of human need, and may persevere in commending the saving Gospel of our Redeemer Jesus Christ; who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
