Saint John, youthful and serene, offers a chalice of deep symbolic meaning—recalling Christ’s words at the Last Supper and the trials he endured for love’s sake. To his side, Saint Peter bears the golden keys and a sacred book, affirming his role as the rock upon which the Church was built. His expression reveals the gravity of his charge, bound by divine trust. Above them, a heavenly angel raises a banner of praise, while below, scenes from their lives unfold—John healing the afflicted, Peter receiving Christ’s call to shepherd. The image evokes themes of spiritual authority, self-giving, and enduring faith.
