The Bible does say we are supposed to judge those in the church. ( 1Cor 5 )I mainly agree with you -- just don't know where you get the 1/3 number of Christians. etc. part. "but not filled and led by the Holy Spirit" -- you're sounding Almost a bit judgemental.
But judgment aside, would you say those "Christians" who support gay lifestyles, abortions, and living in fornication/adultery are Spirit filled Christians?
Step it up a notch, would you say "Christians" that support vandalism and violence are Spirit filled?
Step it up another notch, would you say "Christians" that oppose the Bible and 'sound doctrine' are Spirit filled?
Sometimes we have to judge a little.
