The theology of embrace

I just finished reading the Embrace chapter of Miroslav Volf's Exclusion and Embrace. It is centred around the parable of The Prodigal Son [Luke 15:11-32].
Rather than a theological reading he reads the story at the level of social relationships. The two central themes are "the father's giving himself to his estranged son and his receiving that son back into his household" leading him to pursue the "question of how identities need to be constituted if broken relationships are to be restored."

And he arose and came to his father. But while he was still a long way off, his father saw him and felt compassion, and ran and embraced him and kissed him.
Luke 15:20
