I love this bit from Ilia Delio in The Not-Yet God, summarizing a thought from Franciscan theologian Duns Scotus:

The reason for the incarnation, then, is not sin but love. Christ is first in God’s intention to love. The incarnation is the unrepeatable, unique, and single defining act of God’s love. Thus, even if sin had not entered the universe through the human person, Christ would have come.

That’s good news, my friends.
