I have two hands. I have a left hand, and I have a right hand. Anyone that can understand that, can understand judgement as used in the scriptures.
As I have a left hand, there is a doctrine of judgement that is taught all through the scriptures. I will call this "judging good and evil".
As I have a right hand, there is an obligation that members have to pass over one another's petty faults and flaws. I will call this "passing over one another's petty faults".
These two obligations are as different as left and right are different.
If we can't tell them apart then we can't make sense of the scriptures on the matter.
Our culture has an absolute obsession with "not judging". One can hardly say someone did something wrong. My daughter found herself having to defend the idea that Hitler was an evil person. Her two opponents insisted that to say that would be judging someone.
Our cultural obsession is so strong that even though these are two very different obligations, and even though the scriptures are full of instruction about "judging good and evil", one cannot even discuss the doctrine with people rationally, because they immediately assume you are telling them to go tell each of their neighbors what they think is wrong with them.
We can see how distorted our cultural obsession is by observing how it responds to blunt scriptural teachings. We have scriptures that plainly teach such things as:
1. We must judge righteous judgement. It is given to us to judge, and the way to judge is a plain as distinguishing darkness from light. (There is a very thorough discussion of this doctrine)
2. We must know (i.e. be able to judge) good from evil or be in danger of damnation.
3. Christ condemned the Pharisees for putting aside judgement, which he called one of the weightier matters of the law.
4. Jehovah condemned the Israelites when he looked for judgement and didn't find it.
5. Joseph Smith taught that judgement is an attributed of God that we have to develop just as God has if we are to gain exaltation.
Yet you can read these scriptures and teachings and they are received is as if they are nothing but air. The societal obsession is so overwhelming that even though the scriptures are "as plain as word can be" people won't stop and even given them consideration, much less actually believe them. The sacred cow of "don't do anything that involves that j word" is a jealous cow and won't suffer that we worship anything else,
Which is ridiculous. It is ridiculous that we defy plain scriptural texts in favor of our cultural trends. It is ridiculous that we cannot recognize that the word judging gets used to refer to two different obligations, both of which are explained quite clearly in the scriptures.
