Charles suggested in the comments that I construct my best argument for Christianity as a kind of rhetorical exercise. The fact that the question of Christianity's veracity is something we can reasonably discuss is great evidence against it when leaned against its own claims. As I have stated before, the primary issues I have with Christianity lay on the Ignorance/Knowledge axis rather than the Sin/Salvation axis (an axis, I should point out, we cannot even begin to discuss unless we establish the Ignorance/Knowledge axis - what good is saying "I am sinful and in need of Salvation" if we cannot put our finger out what those words really mean?).

It is the way that Christianity tries to sweep Ignorance/Knowledge under the existential rug which leaves me unable to take it seriously. Of course, the Church has addressed some of these Ignorance/Knowledge questions (quite voluminously, in fact) but to no satisfactory temporal conclusion - starting from immediately after the death of Jesus until this very day, Christendom has never once had a unified conception of his nature, the Church, Sin, Death, Judgement, Salvation, morality, practicality, eschatology, etc. This is most recently and spectacularly demonstrated by the Protestant Reformation and religious movements like Mormonism, New Age, the Doukabours, Bahai and countless others. But Christendom's Cacophony is not new - the Heresy's of the early church are just as numerous and mystifying - Sabellianism, Docetism, Monophysitism, Adoptionism, Nestorianism, Apollinarianism, Arianism, Donatism, Pelagianism, Gnosticism, Manicheanism and others. Not even the Gospels present an entirely consistent or unified view of the nature of Christ and his mission and its relation to our nature and duty, even if we restrict our attention to those canonized ones - if we expand our attention to Gospels not included in the Bible, we see at least that from very, very early on the nature of Christ was confused and the subject to much debate. Conflicts about the nature of Jesus, God, his mission, the Church, have caused a lot of strife, death, and certainly damaged the credibility of the supposed mission of the Church (whatever it might be) throughout the ages. That Christ said very little of these many issues, never said to an Apostle "grab a pen and write what I am about to say about the Trinity down because it will save us a lot of trouble in the future" is extremely bizarre. You would have to be a superhuman to make sense of all of the arguments about Christianity and Jesus did very little to resolve the issue despite the fact that it was (and is) well within his power to do so.

And there is no reason to stop at Christianity - the "People of the Book" cannot even agree on the nature of God the Father and his desires about the world - a very strange state of affairs for a group of people whom routinely claim to speak to God and hear Him speak to them.

This brings me to a point - I am not here arguing against Christianity per se - I am here arguing against a mode of thinking which is credulous enough to believe Christianity and a thousand other things. Chesterton said that when you believe in nothing you will believe in anything, and that may be true of the unprincipled non-believer. I am not that person, however. I believe that the universe has a consistent form, or that we may as well at least assume it does, and that we can know it at least partly, and at great effort, and that effort has revealed a Universe of great beauty and simplicity. One in which there is as little room for Christianity as there is for Hinduism or Islam or Mormonism.

I'd be willing to engage in a defense of Christianity as a kind of lark, but only if Charles will agree to defend Hinduism, a beautiful and highly credible (at least by non-rational standards) religious tradition, or Buddhism or Bahai or Mormonism or Thor Worship.

For the record, the only argument I can imagine being a good one for Christianity in the context of my worldview is "I have received Divine Revelation about the nature of myself and the world and God which informs me directly that the claims made by the Bible and the Church are true." Even the Chruch, with its emphasis on faith and revelation, basically asserts in the end that this is the only real way for a person to know that Christianity is true.
