"Church of Nice" is a Church Militant term for those Catholics who preach toleration of evil but avoidance of the cross. Their vision of a milquetoast Jesus glosses over the moments when Christ wasn't so nice.
If a "nice" person is never angry, abrasive or offensive, then Christ wasn't always nice.
Our Lord did get angry with the Pharisees, who were looking for any excuse to accuse Him, while being closed-minded to His teachings. Mark 3:5 recounts that Christ looked "round about on them with anger, being grieved for the blindness of their hearts."
And if Christ wasn't angry when He drove the money changers out of the Temple with a whip, trashing their tables, then He was at least abrasive, as John 2:15 records: "And when He had made, as it were, a scourge of little cords, He drove them all out of the Temple, the sheep also and the oxen, and the money of the changers He poured out, and the tables He overthrew."
He was also blunt in John 4:18, when He reminded the woman at the well, "For thou hast had five husbands: And he whom thou now hast is not thy husband."
Then again, He didn't mince words in Matthew 17:16, when He declared, "O unbelieving and perverse generation, how long shall I be with you? How long shall I suffer you?"
Many consider name-calling to be offensive, but in Matthew 23:33, Our Lord peppers religious leaders with offensive names: "You serpents, generation of vipers, how will you flee from the judgment of Hell?" He also called them hypocrites, blind guides and whited sepulchers.
He even blasted St. Peter as Matthew 16:23 recounts: "Go behind me, Satan; thou art a scandal unto me."
Of course, we're talking about the God-man, Who in Matthew 10:34 revealed, "I came not to send peace, but the sword."
