Holy Thursday is about the institution on the Holy Eucharist and the Holy Priesthood. The all male priesthood. It has always been a liturgical abuse to wash the feet of women at the Holy Thursday liturgy. It’s still a liturgical abuse. Even if a Pope does it, unless or until he changes the rubrics.
Maybe it’s a minor point. And it’s not a hill I’m willing to die on. I expressed my opinion and that’s pretty much all I’m going to say about it.
Out here in the high west that foot washin’ stuff seems pretty exotic, whatever the gender of the washer/washee. I just yanked off my dusty cowboy boots and found a small dead scorpion mashed on the heel.
