O Lord our God, you call whom you will and send them where you choose: We thank you for sending your servant Willibrord to be an apostle to the Low Countries, to turn them from the worship of idols to serve you, the living God; and we entreat you to preserve us from the temptation to exchange the perfect freedom of your service for servitude to false gods and to idols of our own devising; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
