Expurgate vetus fermentum

The composer Johannes Lupi sets a powerful Latin text from 1 Corinthians 5:7-8, urging the faithful to cleanse themselves of the old leaven so that they may be a new batch, as they are unleavened. Christ, our Passover lamb, has been sacrificed. Therefore, let us celebrate, not with old leaven, or with leaven of malice and wickedness, but with the unleavened bread of sincerity and truth. This motet, scored for SATTB voices, is a profound musical reflection on the Paschal mystery and the call to spiritual purity. Its rich harmonic language and contrapuntal skill are characteristic of sacred music from the period, offering a compelling and moving experience for both choir and listeners.
