Rather bizarrely, I found myself chatting to Rowan Williams recently. I suspect he is both more theologically orthodox, and more passionately concerned with personal holiness than a lot of his critics either are themselves or give him credit for, as well as working much harder.
Of course, that doesn't mean he's a master of soundbites. He's a very bright guy, and a very knowledgeable guy, and he tends to assume that other people can keep up with him. Oddly, if he talked down to people more, he might be easier to understand, but at the cost of being a less nice person.
Compare the following two quotes. Rowan Williams is more accurate, even "sounder" and closer to being comprehensive. But Rico Tice's is a better soundbite.
We are more wicked than we ever realised, but more loved than we ever dreamed.
Rico Tice, Christianity Explored
The human condition is more serious and more terribly damaged than anyone wants to hear; but the resource of God's self-emptying love is greater than we have words to express.
Rowan Williams, Easter Sunday 2010
