No, they're not. And I don't mean that religion and science cannot "coexist" either in the real world, or in somebody's mind. However, if a religious person were to argue that they found the scientific method the supreme way of understanding, for lack of a better term, "stuff," they would be subject to cognitive dissonance. Most religions, in order to be a "believing" member, require fundamentally unscientific things to be accepted as truth.
