On May 16th, 1529, Martin Luther published the Small Catechism. Thanks be to God!
O merciful God, what a kind and gracious Father You are, who deals so sincerely and fatherly with us poor and condemned sinners. You cast Your only Son, Jesus Christ, Your most precious possession, into the jaws of death and the devil. You required that He should descend into the deep and again ascend on high and lead captive the captivity which has held us all in bondage. Through this we are Your dear children, His brothers and heirs of all His eternal, heavenly blessings. Give us Your Holy Spirit so that He may preserve us in faith to the end. Grant Your grace that young people and those unborn, the weak in faith and those not properly instructed may gain and keep a right understanding of the doctrine that they also are privileged to become fellow citizens with the angels. This is the privilege of those who believe in Christ. Amen
