Christianity (n.) is not a doctrine but the fact that the God has existed... if it were a doctrine the relation to it would not be one of faith, since there is only an intellectual relation to a doctrine.
Christianity (n.) is not a social matter, but rather, a deeply personal relationship with God. It is a mere matter of happenstance that there are other Christians in the world with you. It is an extremely individual philosophy.
Christianity (n.) is not interested in changing externals... nor does it want to abolish drives or inclination... rather, it wants only to make infinity's change in the inner being.
Christianity (n.) is profound precisely in that Christ is both our atoner and our judge.
Christianity (n.) has one proof of its truth that unbelief left standing, indeed invented — the proof of 1800 years — which faith contends is blasphemy.
