By Fr. Brian Mullady, O.P., Catholic Exchange - Why did the Son of God become a human being? His Incarnation was not arbitrary, but essential to God’s plan to restore us to His friendship. We can see the perfection of that friendship in Adam... Adam and Eve were called upon to look at the world as God does, and they were able to do so because they had sanctifying grace, and they were able to persevere in doing so because they had actual grace.
