FILTHY RAGS?

There is this idea in pop-Christianity that any good deed done which is not directly motivated by a conscious desire to serve Jesus is actually sinful. Even detestable in God's sight.

(I think maybe this is yet another Calvinist concept that has slipped into the broader Christian tradition. It has "Total Depravity" written all over it.)

One of the proof texts for this idea is Isaiah 64:6:

6 We have all become like one who is unclean, and all our righteous deeds are like a polluted garment.

You might have heard "polluted garment" translated as "filthy rags". The Hebrew words here famously denote soiled menstrual cloths. 

Sounds bad for human righteous deeds, right? They are disgusting in God's sight, right?

But there are two problems here. 

The first is the oft-made mistake of assuming a verse applies to all people at all times. When Isaiah says "we", is he speaking of "we humans" of all times and places or is he speaking of "we Israelites and Judeans" of his own day?

Since he's prophesying to a wayward people at a crucial time in their history, I would lean toward understanding the "we" and "our" as applying to his immediate audience. Maybe the idea of "filthy rags" can be universalized, but we need to understand that this would require an extra step and then build a case for why it should be done. 

The second problem is pulling a verse out of context. 

Notice that Isaiah says "we" have all BECOME unclean, implying that it was not always this way. If the people were not always unclean, perhaps their righteous deeds were not always like filthy rags in God's eyes.

Look, too, at verse 5!

5 You meet him who joyfully works righteousness, those who remember you in your ways.

Seems to me Isaiah is not saying God has a problem with righteous deeds in general - after all, He's willing to "meet" with those who act righteously with joy. 

The problem seems to be when the Israelites think they can balance out their rebellion and sin with a few righteous acts done to placate God. 

That's the old "get drunk on Friday night and go to church on Sunday morning" approach. 

And that approach to "righteous deeds" is rightly repugnant in God's sight.
