The song beautifully describes the trials of Saint Catherine. The very simple musical [bad word] focuses the listener on the stories recounted of the saint's unshakeable faith

Katharine collaudemus
virtutum insignia,
cordis ei presentemus
et oris obsequia,
ut ab ipsa reportemus
equa laudis premia.
Fulta fide Katharina
iudicem Maxentium
non formidat; lex divina
sic firmat eloquium,
quod confutat ex doctrina
doctores gentilium
Victi Christum confitentur
relictis erroribus.
iudex iubet, ut crementur;
nec pilis nec vestibus
nocet ignis, sed torrentur
inustis corporibus. 
Post hec blandis rex molitur
virginem seducere,
nec promissis emollitur
nec terretur verbere; [bad word]  custoditur
tetro clausa carcere.
Clause lumen ne claudatur,
illucet Porphyrio,
qui regine federatur
fidei collegio;
 [bad word] fidem imitatur
ducentena contio.
Huius ergo contionis
concordes constantia
vim mundane passionis
pari patientia
superemus, ut [bad word] bonis
letemur in gloria.
