Jane Austen’s 250th birthday this week is being widely celebrated on this network. She was swathed in the practice of faith: her father and two of her brothers were ordained, and two visits to church on Sunday were her lifelong pattern. She certainly knew the shortcomings of religion: parodying the servility and self-importance of the parson Mr Collins, she says he ‘was not a sensible man, and the deficiency of nature had been but little assisted by education or society.’

Her gift is to turn the interactions of family and community, and especially the elaborate dance and fragility of finding a marriage partner, into a whole moral universe. Her characters transcend their surroundings. One, Mr Bennet, says laconically, ‘For what do we live, but to make sport for our neighbours, and laugh at them in our turn?’ Another, Mr Knightley, says poignantly to Emma Woodhouse, ‘If I loved you less, I might be able to talk about it more.’

It's a truth universally acknowledged that it’s never been clear what it actually means to be a Christian. Some insist on adherence to specific doctrines. Others on obedience to identifiable moral codes. Others point to formation in a traditional culture. A woman of her time, Jane Austen’s participation in worship and devotion was socially conventional. But she has her own answers to this perennial question.

If she were to identify a favourite parable, my guess is she’d choose the story of the two sons, one of whom refused his father’s request to go into the vineyard, but did; while his brother said, ‘I will,’ but didn’t. For Austen, Christianity’s about actions not words. ‘Christian’ is more of a verb than a noun. The many suitors are sifted out not by their protestations of love, but by their true character. Of Fanny Price, we’re told, ‘She made herself indispensable to those she loved.’

Which connects Jane Austen in a significant way to Christmas. For the Christmas story’s not about what God says. It’s about what God does. In Northanger Abbey, Isabella Thorpe exclaims, ‘There’s nothing I would not do for those who are really my friends. I have no notion of loving people by halves. It’s not my nature.’ Coming in person as a vulnerable baby is communicating by action rather than by word. Maybe Jane Austen knew exactly what she thought being a Christian meant. It meant not loving by halves. Perhaps she’s more of a theologian than she’s usually given credit for.
