Christ became obedient for us even to death, death on a cross.
JESUS CHRIST … SUFFERED UNDER PONTIUS PILATE, WAS CRUCIFIED, DIED AND WAS BURIED; HE DESCENDED INTO HELL.
(The Apostles' Creed)
On Holy Saturday the Church waits at the Lord's tomb in prayer and fasting, meditating on His Passion and Death and on His descent into Hell, and awaiting His Resurrection.
