Unity of Religions! How is that possible?

The doctrine of mazhariyya, which turns all religious founders into ‘Manifestations of God’ derives from the esoteric systems of Shi'ism and Sufism, which means that most Sunni Muslims will find it repugnant. Other components of the world religions, from the Jewish halakha to the crucifixion (which Baha’is accept, but which Muslims deny) to the Trinity to circumcision (which Baha’is have abandoned) to Holy Communion to performing the hajj all have to be consigned to the dustbin.
