Lord God, heavenly Father, we thank you for instituting holy matrimony to keep us from unchastity and other offenses. Send your blessing on every husband and wife, that they may not provoke each other to anger and strife, but live peaceably together in love and godliness, receive your gracious help in all temptations and raise their children according to your will. Move us all to walk before you in purity and holiness, to put all our trust in you, and lead holy lives on earth and in the world to come enjoy eternal life; through your beloved Son, Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one true God, now and forever.
