Science teaches us that, where there is an apparent gap in the chain of life, there must be some being which fills it. There was one important deficiency; there was no example of a simple human being who was sinless and full of grace. The only two who were so created hastened promptly to disembarrass themselves of the great privilege at the mere word of the tempter. The completeness of God's work in Creation and Redemption required that there should be an example of what His grace was able to effect in human nature, a being that we could look up to as the ideal of simple creatures in the class below the Divine Man. Many had risen to great holiness by repentance for their sins, others by innocence which they never lost; Jeremias and John the Baptist had further been purified from sin before their birth. Still, in one remote corner of human life Satan had found a strong hold; all were, in the first moments of existence, subject to him by original sin. It was necessary in one case to drive him from that last retreat, and exhibit one being absolutely free from sin and full of all human perfection, For the glory of God, the Blessed Virgin was preserved from even the indeliberate inherited stain of sin; she was conceived immaculate. Honor her as the delight of the Almighty, the highest of His works, the fullest manifestation of His power and holiness, the example of perfect human life among mere creatures.
