You’ve just been promoted to director of liturgy for your diocese. You can accommodate all of the new bishop’s friends and sponsors–not to mention the faithful flock–but you have to book the local convention center to do it. You can, as Michael Sean Winters suggests, make this “dreadful concession.”
Or you can hold to tradition and cram everybody in the cathedral. Assume your bishop is a canon law expert ill-educated in liturgy. He’s leaving the decision to you. Sit in the purple chair and render judgment.
