"Let us rejoice. Sadness is not becoming upon the Birth Day of Life Itself, which, now that the fear of death is ended, fills us with gladness, because of our own promised immortality. No one is excluded from sharing in this cheerfulness, for the reason of our joy is common to all men. Our Lord, the Conqueror of sin and death, since there was no one free from servitude, came that He might bring deliverance to all.
Let him who is sanctified rejoice, for he draws nigh to the palm. Let the sinner rejoice, since he is invited to grace. Let the Gentiles exult, for they are called to life. For the Son of God, in the fullness of time, has taken upon Himself the nature of our humanity, as the unsearchable depths of the divine counsel hath decreed, in order that the inventor of death, the devil, by that very nature which he defeated, would be himself overcome.
And in this contest that was undertaken for us, the battle was waged in accordance with a great and wondrous law of justice. For the Omnipotent God engaged in combat with His most bitter enemy, not in the strength of His own Majesty, but in our human infirmity; confronting him with our very form and nature, and sharing likewise in our mortality; but free of all stain."
“You are from your father, the devil,
and you choose to carry out your father’s desires.
He was a murderer from the beginning,
and he does not abide by the truth,
for there is no truth in him.
When he lies,
he speaks in accord with his own nature,
for he is a liar
and the father of lies."
John 8:44
