The scriptural warning that we will be judged as we judge is not a warning that we are to call nothing evil. The scriptures explain the idea in great detail:
Insofar as we learn to judge by the light of Christ, then when we are judged that light will be found in us.
If the light of Christ is not the light by which we judge then when we are judged that light will not be found in us.
As we judge, we are judged. Is his light the light we see by? Or do we choose another means through which to see the world?
