How do we find out about Jesus. Through the preaching of the Word. What is the Word? The Bible.
C.F.W. Walther the first President of our church wrote in the newsletter that would become the Lutheran Witness –
The Bible is the question of God to man: do you believe My Word? The symbolical writings (Lutheran Confessions) are the answer of men: yes, Lord, we believe what you say! The Bible is the chest in which all treasures of wisdom and the knowledge of God lies hidden. The symbolical writings are the jewel room in which the church has deposited as in a spiritual storeroom all the treasures which in the course of hundreds of years she has with great effort drawn and dug out of the treasury of the Bible. The Bible with its teachings is the handwriting of God concerning our salvation, which Satan always wishes to falsify and declare as unauthentic. The symbolical writings contain the records which have been laid down, from which one can see how the church has believed these teachings from time to time and has ever held fast to them.
Oh, let us, then be on guard against those who refuse to build on the building of the church’s past but would build something new. Consider what the apostle wrote in Ephesians 4 that there is one body, one faith, one baptism, hence also one true church and one correct doctrine, which does not have need to be found for the first time, but which always was and will continue unchanged until the end of days, so that all new doctrines and new churches are false doctrines and false churches . . . Thus we participate in the victory of all true contenders for the unadulterated Word of God and become fellow heirs to the full blessings of the Reformation. (Jan. 23, 1849)
