What is the aim of the third commandment?

That we neither blaspheme nor misuse the name of God by cursing,¹ perjury,² or unnecessary oaths,³ nor share in such horrible sins by being silent bystanders.⁴ In summary, we should use the holy name of God only with reverence and awe,⁵ so that we may properly confess God,⁶ pray to God,⁷ and glorify God in all our words and works.⁸
