Seems to me that there is terrifically arrogant presumption in the idea that "we, our group" knows the only way to the divine, an eternal creator (or knows about the eternal creator, or <insert divine being of choice>). To presume that any such creator NEVER before and NEVER since has shown evidence of itself to anyone else or any other culture in time, except one particular group of individuals, one particular culture, at one given time; that all others expressing their own experience of the divine is not real, is the work of a Satan like character, or a deception by evil, seems magnificently myopic, self servingly selfish, and remarkably limiting and insulting of any such creator. Should any such prime mover/creator exist, I would be far more likely to believe that millions since the dawn of time, in many varied cultures have become witness to the divine and only an insecure ego would demand and defend their own experience of the divine as being "the one and only way".
When it comes to the Bible and Christianity, it makes little difference and carries absoutlely no weight that it speaks of itself as being 'the only way', the only scripture directed by the divine. While it is possible that there has been some divine inspiration for some of the contents of the Bible, the tinkering, tampering and direction of men have clouded this through their own selfish shortsightedness. There are other writings from other cultures that equally speak to/of the divine. There is no monopoly on the possibilities of true religious experiences originating from any eternal and divine entity.
