Pope St. Caius stayed *hidden in the Catacombs for 8 years to preserve himself for His flock.
The Saint was eventually captured and martyred (via decapitation). St. Caius' tomb,
with the original epitaph, was discovered in the catacomb of Callixtus
*"St. Caius encouraged St. Sebastian, and the other martyrs
and confessors. However, to preserve himself for his flock, he withdrew for a time, to avoid the fury of the storm." (Source: "The Lives of the Primitive Fathers, Martyrs, and other Principal Saints", by Rev. Alban Butler, Vol. IV pp.
232-233, Edinburgh, 1799 A.D., Imprimatur) Note: also see the ancient (original) Liber Pontificalis historical account of the life of Pope & Martyr St. Caius, attributed to the Church Father & Doctor, St. Jerome. -ED
