If a theologian is asked to yield and make concessions so that peace may at last be established in the Church, yet if he refuses to budge on even a single point of doctrine - to human reason this looks like excessive stubborn-ness, even like downright evil intent. This is why such theologians are rarely loved or praised during their lifetime. On the contrary, they are scolded as disturbers of the peace or even as destroyers of the kingdom of God. They are regarded as men worthy of contempt. But at the end of the day it becomes clear that the very determined, unfailing tenacity of these theologians as they cling to the pure teaching of the divine Word by no means tears down the Church. On the contrary, it is this very attitude that even amid the greatest dissension--builds up the Church and ultimately brings about genuine peace. Therefore, woe to the Church if it has no men of this stripe-men who would stand watch on the ramparts of Zion, sounding the alarm whenever a foe threatens to rush the walls, men who would rally to the banner of Jesus Christ, ready for a holy war!

— C. F. W. Walther, Law and Gospel: How to Read and Apply the Bible, 32—33.

Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.

1 Corinthians 15:58
