Church people are generally pharisees. They like gloating rather than rebuking or reproving.
 Two men went up into the temple to pray; the one a Pharisee, and the other a publican.
 The Pharisee stood and prayed thus with himself, God, I thank thee, that I am not as other men are, extortioners, unjust, adulterers, or even as this publican.  I fast twice in the week, I give tithes of all that I possess.  And the publican, standing afar off, would not lift up so much as his eyes unto heaven, but smote upon his breast, saying, God be merciful to me a sinner.  I tell you, this man went down to his house justified rather than the other: for every one that exalteth himself shall be abased; and he that humbleth himself shall be exalted.— KJV, Luke 18:10-14
The pharisee is self righteous, similarly to gloating.
The pharisees rebuke Jesus for eating with publicans and sinners.
 And when the Pharisees saw it, they said unto his disciples, Why eateth your Master with publicans and sinners?
 But when Jesus heard that, he said unto them, They that be whole need not a physician, but they that are sick.  But go ye and learn what that meaneth, I will have mercy, and not sacrifice: for I am not come to call the righteous, but sinners to repentance.— KJV, Matthew 9:11-13
Jesus calls them vipers.
But when he saw many of the Pharisees and Sadducees come to his baptism, he said unto them, O generation of vipers, who hath warned you to flee from the wrath to come? — KJV, Matthew 3:7
