Fitzgerald further argues that the aim of interreligious dialogue is not to produce a new world religion or to achieve some sort of theological unity between all religions. In this it differs radically from ecumenical dialogue conducted with the various Christian churches with a view to a unity of worship grounded on a unity of faith. Indeed, theological dialogue with followers of other religions, the 'dialogue of discourse', is especially difficult due to the divergence of beliefs, and requires participants with a thorough theological education, but such dialogue can serve to eliminate false problems. Other forms of dialogue are important, such as the dialogue of life, the dialogue of action and the dialogue of religious experience.
