Book of Saints – Castus and Secundinus


CASTUS and SECUNDINUS (Saints) Bishops, (July 1) Martyrs (Date unknown) Two Saints much venerated in various churches of Southern Italy, and celebrated by several Mediaeval authors. The Martyrologies register them as of Sinuessa (Mondragone) near Caserta. Saint Castus is often written Saint Cassius. A Bishop Secundinus assisted at the Council of Sinuessa A.D. 304. Detailed accounts of them were written some fifteen hundred years ago, but the Bollandists and other modern authorities put little faith in their accuracy.
