One of those odd coincidences that make you smile, and pray thank you, and smile again.

That AOL voice with the mid-western accent, announced "You have email" – which on checking, I discover an update from Amazon. "Your order has shipped" – meaning Jurgen Moltmann's now out of print little gem, Theology and Joy, was on its way in time for Christmas.

The coincidence? I'd just finished reading, and marking in my book, the following from Dorothy Day, just after her child Tamar was born. Maybe a self-conscious echo of Mary's heart leaping at the annunciation:

"No human creature could receive or contain so vast a flood of love and joy as I often felt after the birth of my child. With this came the need to worship and adore."

Gratitude. Joy. Worship. Adoration. And thus the connection between Theology and Joy.
