Lord God, heavenly Father, You preserved the teaching of the apostolic Church through the confession of the true faith at Augsburg. Continue to cast the bright beams of Your light upon Your Church that we, being instructed by the doctrine of the blessed apostles, may walk in the light of everlasting life; through Jesus Christ, Your Son, our Lord, who lives and reigns with You and the Holy Spirit, one God, now and forever. Amen.
