This audiobooks was made from excerpts of: The Life of Saint Cecilia published in America in 1866, translated from the French of Dom. Prosper Gueranger and is in the public domain.

St. Sebastian was named defender of the Church by Pope St. Caius.  As Captain of the Imperial guard to the Emperor St Sebastian used his position to win converts, strengthen those facing martyrdom and aid Christians with his ability to work miracles.  He also had the rare privilege of being martyred twice for Christ sake.  Be inspired by his heroic life and martyrdom and learn from his most noble heart love of God and country.

This story is taken from the Acts of the Martyrs, translated by Fastre SJ from 1871
