When the Homily is about Immunology

Anger

Never correct someone with anger, but only with humility and sincere love. When you see anger ahead, forget about correcting for a moment. When peace has returned, then your powers of discernment are functioning properly and then you can speak beneficially. Since man was created rational and gentle, his is corrected far better with love and gentleness. An angry and irritable man is not accepted into the Kingdom of God even if he raises the dead. Therefore, suppress anger with all of your might, and you will find it weaker the next time.

Doubtfull that Elder Joseph had kids, but I'll try anyway.
