THE SOUL OF JESUS CHRIST, immediately after His Death, went to Limbo, to announce to the spirits of the just the glad tidings that the work of Redemption was accomplished, and that they would soon ascend with Him to heaven. It was for this reason that our Lord said to the penitent thief: "This day shalt thou be with Me in paradise." Our Lord's Divinity was inseparably joined to His Soul.
