Jesus must never have said the rosary either
Matthew 15:21-28 – Calls the Canaanite woman a “dog”, which was a terribly insulting and would prick the Canaanite woman directly – she was not a Jew, the first group Jesus is sent to.
Matthew 23 (the entire chapter) – first he says the Jewish leaders are hypocrites and the Jesus should do what they say, but not what they do. Then Jesus gives the 7 woes (full of sarcasm), then he calls the leaders “snakes, you brood of vipers”
Mark 12:24 – Jesus asks the Sadducees “are you not in error because you do not know the Scriptures of the power of God?” These were leaders who prided themselves on knowing Scriptures, so this was a terribly sarcastic and insulting statement.
John 9 – the story of the blind man is FULL of sarcasm, but most from the blind man (and his family). Jesus last statement to the Pharisees is very sarcastic too – calling them blind.
Luke 13:31 – Jesus calls Herod a fox, but he uses the feminine of the Greek word, which means he is calling him a vixen. Now that is an insult!
After recently having paid more attention to the Religion Forum lately than I used to, I've been reviewing certain passages (mainly in the New Testament letters) about speech and related conduct. They're interesting, especially when read in contrast to what sometimes happens in the Religion Forum. Consider, for example, Philippians 4:5, and how often those who identify as Christians practice it.
Whether or not the rosary helps defeat sarcasm--and I'm not going to pass judgment on that question right now--sarcasm seems less important "biblically" than the world tries to make it sound. Although I don't see a total biblical prohibition of sarcasm, whether by command or by example, and one can arguably point to examples of the use of sarcasm by "good people" in the Bible, neither point seems to commend sarcasm as a leading virtue in Christian speech.
Unless I'm missing something big, I'm not aware of any command to cultivate one's sarcasm skills, even on behalf of apologetics or for some other presumably pressing reason. Unless I'm missing something big, certainly the Bible doesn't seem to commend sarcasm as one's dominant mode of speech or posting. I'm not even sure that sarcasm helps much against Boko Haram.
Thanks for the compliment.
