A close family member has the habit of detraction about practically everyone. Especially when speaking to his mother. I seriously try not to eavesdrop, but he speaks loudly and it's difficult not to overhear. I even turn on loud appliances sometimes so I can't hear. It hurts me to hear him tell all the faults, real or imagined, first-hand or hearsay, about people I either care for or have compassion for (either in my own family, social circle, or in general) When they are speaking it's just a litany of ridicule about the faults, faux pas, and idiocy of other people that they either know or have heard of. It literally makes me sick to my stomach.  I am also pretty sure he does it regarding myself, since I doubt I hold any special immunity.  It really bothers me, but I don't know if it's my place to correct this person. I know he would be angry and defensive if I point out the seriousness of the sin of detraction to him. Should I just say nothing?

Yes, he should be challenged for his own good and for the good of all.

Would saying to him do any good?

St. Thomas lays out the criteria for when rebukes are necessary and permitted.

Will it do any good?  Are you in a position of authority over the person?

OP here, thank you all who answered. After thinking awhile, I really don't think it would do any good. It would just anger him and make him defensive. So I'll just keep quiet and continue praying for him.

If you think it wouldn't do any good then you shouldn't say anything.

As if your LYING is a good thing???

Maintaining a prudential silence for the sake of charity is not the same as lying.

It is not "prudential silence" to falsify Scripture for your convenience or protect your pride.
It is not "prudential silence" to claim Jorge preached against the тαℓмυd when he did not mention the тαℓмυd.
It is not "prudential silence" to claim Jorge acknowledged differences between Judaism and the One True Faith when JOrge instead preached indifferentism.
LYING is not "prudential silence."

You do not have to use the word 'тαℓмυd' to preach against it.

In the talk in which you claim Francis was preaching against the тαℓмυd few people would have recognized any connection to the тαℓмυd.  Those of us with sufficient background knowledge understand that the Scripture that Francis quoted is a condemnation of тαℓмυd.  Most people do not have that level of knowledge and would not have understood it that way.  They are more likely to have understood allusions to the "traditions of men" as a condemnation of traditional Catholics (whom Francis is known to dislike) than criticism of Jews (whom he is known to favour.)  Given his history, he probably intended that it be understood that way.

It is completely dishonest to claim that this was preaching against the тαℓмυd. It is so obviously untrue that I find it hard to imagine that you expect any one to believe it. I suspect that you are only saying it to provoke Mark.
