Am I right in thinking that the clerus almae Urbis historically wear birettas without those French bobbles? and that, as clergy directly subject to the Roman Pontiff, clergy of the Ordinariate fall into that category (together with Redemptorists, Oratorians .... anybody else?)
Will such clergy need to borrow their wives' scissors on the morning of incardination?
And how about those sixteenth century Roman collars worn by Redemptorists and Oratorians?
I shall delete comments which make nasty insinuations about the priorities of Anglican Catholics.
