Someone painted the altar green

The culprit remains unseen
But I swear, sisters, brothers;
I'll cease the weeping of your mothers
And slice that villain clean and quick
On our wall his corpse will stick

For the Lord gave me the power
To protect those who cower
Away from Satan's servants and friends
Don't worry, they are too late to make amends
We can't help that vandal abandon his evil ways
Next thing you know he'll set our church ablaze

So what do you say, sisters, brothers?
He made our altar unlike the others
Now it's our turn to make it clean
And rid the world of all paint that's green
