I call myself a Christian by defining 'a Christian' as 'a person willing to profess the Apostles' Creed.' I am willing, unlike most of my friends – many more moral than myself – to profess it (which does not mean understand it, or fill its every syllable with the breath of sainthood), because I know of no other combination of words that gives such life, that so seeks the crux. The creed asks us to believe not in Satan, but only in the 'Hell' into which Christ descends. That hell, in the sense at least of a profound and desolating absence, exists, I do not doubt; the newspaper gives us its daily bulletins. And my sense of things, sentimental I fear, is that wherever a church spire is raised, though dismal slums surround it, and a single dazed widow kneels under it, this Hell is opposed by a rumor of good news, by an irrational confirmation of the plenitude we feel is our birthright.Quoted without citation in The Faith is Still There by David H.

One might wish for something a bit more robust from Updike. I do. Still, I find his almost wistful believing poignant. And there is something beautiful about the idea that a lonely voice professing the creed opposes the powers of Hell with a rumor of good news and "an irrational confirmation of the plenitude we feel is our birthright". Of course, that plenitude is our birthright, but we traded it for the lentil stew of our sin and idolatry.
For something more robust from John Updike there is his poem, Seven Stanzas at Easter.
