This iconographic portrait captures Saint Peter in a moment of interior prayer, reflecting the intersection of human frailty and divine grace. Dressed in the red of martyrdom and the blue of humanity, he stands as the archetype of the penitent believer—one who holds the keys to the Kingdom only because he first experienced the depth of Christ’s mercy. The expressive brushwork within the halo signifies the "uncreated light" of God permeating a life once defined by the sea, now transfigured by faith.
