Religion as a binding factor falls apart in a society where it's trivial to encounter multiple someones with a different holy book than yours, each who claims theirs is the only correct one.
only if that religion claims exclusivity in exclusion to others. in order to address todays problems a religion must not do that but it must be inclusive and open to all. technically, at least to a degree the abrahamic religions do that in that they do claim that their predecessors are genuine and their followers are considered people of the book. the fact that many members today reject them is a misinterpretation of their respective holy words.
a modern religion must be inclusive to all others, not just the abrahamic religions. at least all those who expect a return of their prophet which is the case not only for all abrahamic religions but at least also for buddhism, hinduism, zoroastrianism, and even native american religions. (there may be others, but i am not familiar with those)
