St. Catherine of Siena recommended perpetual continence ("angelic continence" or spiritual marriage ) to at least two married couples: 1. Giovanni Trenta of Lucca & Monna Tora of Lucca in 1376 (*Letters* vol. 2, pp. 51-4) 2. Ristoro Canigiani & Alessandra (Sandra) Quaratesi in 1378 (*Letters* vol. 3, pp. 209-12) Did other saints recommend perpetual continence to married couples? cf. "Do married couples need to live sexually? "
