So you see, “Anonymous Coward”, there was dissension in the early Church about whether wrongdoers ought to be publicly shamed. Scriptures such as “Judge not, that you be not judged” were written, but so was the above text.

And there is another New Testament reading to reprove before all onlookers those who practise sin, but it is in the 1st epistle to Timothy, that is probably a 2nd century forgery.

These days, in many formerly Christian countries, many people including churchgoers have a blurred incorrect image of Christ as “Gentle Jesus, meek and mild” turning the other cheek and spraying forgiveness around indiscriminately. On the contrary, Christ had a balanced character. He not only taught love and helped people, but he also had a firm side. He did not hide his robust dislike of supposedly “religious” people who used religion as a mask for their misdeeds — he chased traders and moneychangers from the temple (Matthew 21:12, Mark 11:15, Luke 19:45, John 2:15-16), and railed against “religious observers” who were dyed-in-the-wool hypocritical evildoers (read his speech “Woe to you, Scribes and Pharisees, hypocrites” — Matt. 23:13-35, Luke 11:39-52). Wouldn’t you say that clergy who teach purity and continence, but seduce children, are the modern-day equivalents of the Scribes and Pharisees? — John Massam, Perth, Western Australia.
