This feast originated towards the end of the fifteenth century, and was instituted by the private authority of some bishops in Germany, Scotland, England, Spain, and Belgium. The Office and the Mass composed by Bernardine dei Busti (d. 1500) were approved by Sixtus IV. The feast was officially granted to the Franciscans 25 February, 1530, and spread over a great part of the Church.
The Office used at present is nearly identical with the Office of Bernardine dei Busti. The hymns “Jesu dulcis memoria“, “Jesu Rex admirabilis“, “Jesu decus angelicum“, usually ascribed to St. Bernard, are fragments of a very extensive “jubilus” or “cursus de aeterna sapientia” of some unknown author in the thirteenth century. For the beautiful sequence “Dulcis Jesus Nazarenus” (Morel, “Hymnen des Mittelalters“, 67) of Bernardine dei Busti the Franciscans substituted a prose sequence of modern origin: “Lauda Sion Salvatoris“.
