On the contrary, this is one of its weak points. Nevertheless, the Bible, in spite of its weaknesses, has many good things and, above all, It generated a new civilisation. We all, believers or atheists, are products of this civilisation, particularly if we are Europeans, Americans or Australians. By tradition and culture, we are Christians in all that we do, in all our acts. The atheists themselves are Christians without knowing it.
All religions come to similar conclusions.
Because of the priests. The disputes among the Christian cults and sects are not against the Bible but against each other, particularly among the priests. Priests are important because they have to interpret the Bible to the common people. Unfortunately, during the history, many of them made many mistakes, particularly entering politics. In their disputes, they use, without knowing the same argument one other, no matter what sect they belong to.
