Islam has never been hostile to christianity.Indeed it opened the possibility of dialogue from its very beginning.You will find the nearest inaffection to the faitful are those who say,We are christians.That is because there are priests and monks among them and because they are free from pride.Reverence to jesus christ and to his chaste mother is a part of the muslim's creed and remember the angels words to mary.They said Allah has chosen you.He has made you pure and exalted you above all women.
