A good simile for a certain rugged tenacity, in this case referring to the nascent Christian community as it emerged from being a possibly evanescent sect into a full blown religion. ‘Because it thought of itself as ‘the true Israel’, the Christian community was able to remain rooted in every town in which it was established, like a limpet on a rock when the tide recedes.’ Peter Brown’s vivid writing brings to life an era rich in ideas and vitality, which yet often appears remote, benighted and somehow colourless.
