St. Thaddeus, one of the twelve apostles, is depicted in solemn reverence, framed by gothic tracery and radiant stained reds and blues that suggest divine mystery. He clutches a sacred book, symbol of the Gospel he carried to distant lands, while his staff points to his role as a traveling witness of Christ’s resurrection. His downcast yet steadfast gaze invites quiet reflection, drawing the viewer into the legacy of discipleship and endurance. The architectural canopy above his head echoes heavenly majesty, a visual affirmation of his apostolic calling and heavenly reward.
