Why is Saint Sebastian always naked?

Answer 1

Usually the pictures you see of St. Sebastian show him being executed and naked. He would normally have worn clothing, however.

Answer 2

Saint Sebastian is often depicted as partially or fully naked in art to emphasize his martyrdom and purity. The nudity serves as a symbol of his vulnerability and openness to divine grace during his persecution and eventual death. It also highlights the physical torture he endured, such as being shot with arrows, as a testimony to his unwavering faith.
