Gerhard and Walther

All the saints, even if they were exalted and decorated by God, busied themselves with humility.—Johann Gerhard, Schola Pietatis III:222.

When Christ tells us not to judge and condemn, it does not mean no one is permitted to judge and condemn false doctrine or openly proclaim God’s judgment of unbelieving and wicked people…. This applies not only to preachers but also to the laity. They, too, should confidently reject and condemn false doctrine and a godless life.—C. F. W. Walther, God Grant It!, p. 542, 543.
