A very interesting Missale from 1759AD has a Sequence for the Epiphany, but I don’t know where one could find the musical notation. The Seqence is called: “Prompto Gentes Animo Ferte Nunc Altissimo Honorem Et Gloriam.”
“A much greater source of anxiety to Us is the style of action of those who maintain that liturgical worship should shed its sacred character, who foolishly say we should substitute for sacred items & furnishings ordinary common things in daily use.” —Pope Saint Paul VI (14 Oct 1968)
