Church people are generally pharisees. They like gloating rather than rebuking or reproving.
Church people generally are self righteous, similarly to gloating.
 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
Jesus calls the Pharisees 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
