I could be wrong, but didn't pre-Vatican II priests regularly visit the sick, administer the necessary sacraments, celebrate Requiem (Funeral) Masses, as well as the regularly scheduled Masses?  I'm almost 52, so I didn't live in this era, but it's my impression they did.  This doesn't sound like a pre-Vatican II priest or a restorationist. He sounds like a pre-Vatican II liturgical reenactor who attends events when he is available.  I have my doubts that he and the others are "steeped in doctrine and theology" as described.  That's giving them credit they don't deserve.  They sound like a group more into arcane minutia, delicate lace and appliques.
