O God, our refuge and our strength, who raised up your servant Martin Luther to reform and renew your Church in the light of your word: Defend and purify the Church in our own day and grant that, through faith, we may boldly proclaim the riches of your grace, which you have made known in Jesus Christ our Savior, who, with you and the Holy Spirit, lives and reigns, one God, now and for ever. Amen.
