Once again, wouldn't this require a judgement? :)

Sorry.  I couldn't resist.  As you know the misuse of the Scripture "Do not judge" is one of my pet peeves.  Here is just another example to demonstrate that that one Scripture is not a total prohibition on judgement among Christians. 

1 Thessalonians 5:21(NKJV)

Test all things; hold fast what is good. 

If we are to "hold fast what is good" it requires us to make a judgement as to whether something is good or evil does it not?  Hmm?

Notice the beginning of the verse.  "Test all things".  Test them how?  Simple.  Test them against Scripture!
