Indeed, Chocolatelovinggran:
but if we are to "compare" both religions and the reading matter we have to look at both the Koran and the Bible as a whole, becuase the Koran has peace loving and demands to give charitably too. (if you read the details win the reference above).
Many Christians do use the old testament and always have done. Thats not a criticism, just a comment.
Sadly people will cherry pick to find what they want to justify their actions - just look at the use of the bible some right wing sects in the USA do, as regards a number of social issues.
simple example - they will pick on St Paul saying "wives obey your husbands" but miss out the many good things he did say.
