Homily from Mass in the Night (B16)
It would be a false interpretation to see this exclusively as the action of God, as if he had not called man to a free response of love. But it would be equally mistaken to adopt a moralizing interpretation as if man were so to speak able to redeem himself by his good will. Both elements belong together: grace and freedom, God’s prior love for us, without which we could not love him, and the response that he awaits from us, the response that he asks for so palpably through the birth of his son. We cannot divide up into independent entities the interplay of grace and freedom, or the interplay of call and response.
