religion is not a gift from our parents but a legacy to our children. As such it must be preserved and be transmitted duly from a generation to another. Unfortunately, religion is being deprived from its legendary values structured around dialogue, peace, love and tolerance. Our paper is a try to highlight religious dialogue and its impediment through the Trilogy by Chinua Achebe by focusing on the one hand, on major illustrations of religious dialogue; by underlining on the other hand, some obstacles to this very religious dialogue due to many socio religious-bound factors and aspects.
