Faith is more basic than language or theology. Faith is the response to something which is calling us from the timeless part of our reality. Faith may be encouraged by what has happened in the past, or what is thought to have happened in the past, but the only proof of it is in the future. Scriptures and creeds may come to seem incredible, but faith will still go dancing on. Even though (because it rejects a doctrine) it is now described as "doubt". This, I believe, is the kind of faith that Christ commended.
