And he dreamed, and behold a ladder set up on the earth, and the top of it reached to heaven: and behold the angels of God ascending and descending on it.
All Commentaries on Genesis 28:12 Go To Genesis 28
Chromatius of Aquileia
AD 407
Through the resurrection of Christ the way was opened. Therefore with good reason the patriarch Jacob relates that he had seen in that place a ladder whose end reached heaven and that the Lord leaned on it. The ladder fixed to the ground and reaching heaven is the cross of Christ, through which the access to heaven is granted to us, because it actually leads us to heaven. On this ladder different steps of virtue are set, through which we rise toward heaven: faith, justice, chastity, holiness, patience, piety and all the other virtues are the steps of this ladder. If we faithfully climb them, we will undoubtedly reach heaven. And therefore we know well that the ladder is the symbol of the cross of Christ. As, in fact, the steps are set between two uprights, so the cross of Christ is placed between the two Testaments and keeps in itself the steps of the heavenly precepts, through which we climb to heaven.
