Can Christians Ever Judge?

Matthew 1:1–7

1:1 The book of the genealogy of Jesus Christ, the son of David, the son of Abraham.

2 Abraham was the father of Isaac, and Isaac the father of Jacob, and Jacob the father of Judah and his brothers, 3 and Judah the father of Perez and Zerah by Tamar, and Perez the father of Hezron, and Hezron the father of Ram, 4 and Ram the father of Amminadab, and Amminadab the father of Nahshon, and Nahshon the father of Salmon, 5 and Salmon the father of Boaz by Rahab, and Boaz the father of Obed by Ruth, and Obed the father of Jesse, 6 and Jesse the father of David the king.

And David was the father of Solomon by the wife of Uriah, 7 and Solomon the father of Rehoboam, and Rehoboam the father of Abijah, and Abijah the father of Asaph,

1 Corinthians 11:31

31 But if we judged ourselves truly, we would not be judged.

1 John 4:1–3

4:1 Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world. 2 By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God, 3 and every spirit that does not confess Jesus is not from God. This is the spirit of the antichrist, which you heard was coming and now is in the world already.

1 Corinthians 5:9–13

9 I wrote to you in my letter not to associate with sexually immoral people—10 not at all meaning the sexually immoral of this world, or the greedy and swindlers, or idolaters, since then you would need to go out of the world. 11 But now I am writing to you not to associate with anyone who bears the name of brother if he is guilty of sexual immorality or greed, or is an idolater, reviler, drunkard, or swindler—not even to eat with such a one. 12 For what have I to do with judging outsiders? Is it not those inside the church whom you are to judge? 13 God judges those outside. “Purge the evil person from among you.”
