Gerhard and Walther

However, an even greater reason why God the Lord commanded us to sanctify His holy Name is that we, on account of our inherited sin, are by nature inclined towards disrespect and abuse of God’s Name. Hereby [in the second commandment], He desires to guard us from such uncivil behavior.—Johann Gerhard, Schola Pietatis III:260

Oh, may each of us truly receive Christ from the heart, for whoever appears before God in his own righteousness, without Christ, will not stand.—C. F. W. Walther, God Grant It!, p. 574.
