So here's what Tim Shoy says,

I'm convinced that in scripture,

profanity is largely about irreverence,

a trivializing disrespect for God,

for people, for what is holy, beautiful, majestic, good,

or even terrifying, such as hell and damnation.

We are profane when we fail to revere God's holiness,

honor His law, fear His justice,

respect the image in others,

or gratefully enjoy His creation.

Profanity then is not about the number of letters in a word.

It's about the way we treat,

talk about or fail to have reverence or enjoy

people and things God has created.

Profanity is a bad thing, not primarily

because it talks about bad things,

but because it talks badly about good things.

These good things encompass all God has made,

including humans made it his image.

And then He goes on to quote Matthew 5, 2, 1, 22,

you have heard that it has been said,

you shall not murder,
