The homily is supposed to be preached on the subject matter of the Gospel, perhaps drawing on the other readings (which are deliberately chosen to tie-in with the Gospel).
It would be inappropriate for a priest to use his homily to discuss “current events” unless they were relevant to the Gospel.
Had the Gospel been about the wedding at Cana, perhaps it would have been appropriate.
But, since the Gospel had nothing to do with marriage, my priest did not bring it up. My priest is good about avoiding liturgical abuses.
Protestant sermons are often focused on “current events.” Protestants don’t have a prescribed cycle of readings. I’m sure the wedding at Cana was brought up in many protestant services last Sunday. But Catholic worship is not driven by current events. Priests don’t get to pick the readings each Sunday, and it would be a liturgical abuse to significantly deviate from the subject matter of the Gospel.
