James 4
11†Do not speak evil of one another, brethren. He who speaks evil of a brother †and judges his brother, speaks evil of the law and judges the law. But if you judge the law, you are not a doer of the law but a judge. 12There is one Lawgiver, †who is able to save and to destroy. †Who are you to judge another?

That's of brothers.
There's no indication that Osteen is a believer.
The other thing is, error is to be exposed.
We are commanded to use discernment in testing the spirits to see if they are of God or not.
We HAVE to judge to do that.
It appears that what escapes the notice of most people is that we judge every day of our lives. We are always in the position of making a determination of whether something is true or not, safe or not, advisable or not. That all requires making judgments.
And judging that someone is good is also a judgment, except that you never hear anyone quoting *Do not judge* at someone when they say something good about someone. It's only when the judgment is unfavorable, EVEN WHEN IT'S TRUE, that people are pummeled with verses about not judging.
If people don't use discernment and make sound judgments, they are open to all kinds of deception. It has to be done, but must be done according to God's standards. And that includes exposing false teachings and false teachers.
I never speak poorly of a brother.
The thing that escapes many here is that Osteen is not a brother. He is a ravenous wolf.
