With the Loudest Voice

"If I profess with the loudest voice and clearest exposition every portion of the truth of God except precisely that little point which the world and the devil are at that moment attacking, I am not confessing Christ, however boldly I may be professing Christ. Where the battle rages, there the loyalty of the soldier is proved; and to be steady on all the battlefield besides, is mere flight and disgrace if he flinches at that point." Martin Luther

Along the same lines, Luther also said this: ""If we are correct and right in our Christian life at every point, but refuse to stand for the truth at a particular point where the battle rages--then we are traitors to Christ."
