If you would like to change the references it would behoove you to start your own post. As for Holy Scripture, including the Epistles, all are good for instruction and edification, but it must be with understanding. I am certain there are not better instructions on judgement than the teachings of our Master(Teacher). So let us remain on the OP content. Christ is the Word, this He as a reference should be sufficient for any who claim t follow Him.
1 Corinthians 5:9-13. Is related to your op as it is about righteous judgement. Truly, unregenerated men are unable to apply righteous judgement and should never judge others or condemn them because they are both blind and would only be found to be hypocrites. This does not apply to regenerated men who's eyes can see the whole light of truth. Perhaps the meatier subjects in the Scriptures are to advanced for the intended purposes of edification here in this particular thread. It is our duty as regenerated men to apply righteous judgement. We are overseers of the flock appointed by Christ Himself. Do we not love our brothers and sisters in Christ by speaking the whole truth to them?
1 Corinthians 5:9-13 is in the context of judgement and related to Matthew 7:1-6 and Luke 6:37-42. If you are unable to apply the whole context of what Christ has instructed to the church in the NT you are not a workman approved and show yourself to be a mere babe lapping at milk at best. Please consider these things.
Matthew 7:1-6 1Judge not, that ye be not judged. 2For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again.
3And
why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye? 4Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam
is in thine own eye?
5Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother's eye. 6Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.
Christ is speaking to unregenerated Jews living in the first century who had not received the dawning of the Holy Spirit yet, these were told not to judge or condemn as they had no ability to discern what was right and true without Christ having sent the Holy Spirit to them ("the Spirit of truth"). They were still carnal and unfit to judge spiritual things,practicing judgement in these matters would only lead to hypocrisy. The same thing applies to unregenerated men today. Pulling one verse out of the Scriptures without looking at the whole context does not always edify. Surely you know this.
Luke 6:37-42 Judge not, and ye shall not be judged:
condemn not, and ye shall not be condemned: forgive, and ye shall be forgiven:
38Give, and it shall be given unto you; good measure, pressed down, and shaken together, and running over, shall men give into your bosom. For with the same measure that ye mete withal it shall be measured to you again.
39And he spake a parable unto them,
Can the blind lead the blind? shall they not both fall into the ditch? 40The disciple is not above his master: but every one that is perfect shall be as his master. 41And why beholdest thou the mote that is in thy brother's eye, but perceivest not the beam that is in thine own eye?
42Either how canst thou say to thy brother, Brother, let me pull out the mote that is in thine eye, when thou thyself beholdest not the beam that is in thine own eye? Thou hypocrite, cast out first the beam out of thine own eye, and then shalt thou see clearly to pull out the mote that is in thy brother's eye.
John 16:7-15 Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.
8And
when he is come, he will reprove the world of sin, and of righteousness, and of judgment:
9Of sin, because they believe not on me;
10Of righteousness, because I go to my Father, and ye see me no more;
11Of judgment, because the prince of this world is judged. 12I have yet many things to say unto you, but ye cannot bear them now.
13Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear,
that shall he speak: and he will shew you things to come.
14He shall glorify me: for he shall receive of mine, and shall shew
it unto you.
15All things that the Father hath are mine: therefore said I, that he shall take of mine, and shall shew
it unto you.
Good day to you sir
