“Sing, my tongue, the Savior's glory,
Of His Flesh the mystery sing;
Of the Blood, all price exceeding,
Shed by our immortal King.”
Pange, lingua, gloriosi
Corporis mysterium
Sanguinisque pretiosi,
Quem in mundi pretium
Fructus ventris generosi
Rex effudit gentium.
Thomas Aquinas (1225–1274) Italian Dominican scholastic philosopher of the Roman Catholic Church
