You have to be very clear about what "religious teachings" you're referencing. If you're referring to Judaeo-Christian thought, I have no comment. But if you're referring to the tenets of Hinduism, a far more ancient religion, and probably the oldest extant faith in the world, then you're quite wrong.
Hinduism, as described in one of the Upanishads, distinguishes the "Atman" or Self, which is the actual soul, from its five sheaths (called "Koshas") - namely the Annamaya Kosha (food-sheath), Pranamaya Kosha (vital sheath), Manomaya Kosha (mental sheath), Vijnanamaya Kosha (intellect-sheath) and Anandamaya Kosha (blissful sheath). These sheaths, which go from the grossest physical self to the deepest emotional core, are responsible for all conscious and even unconscious (dream-state) experience, volition, intellect, pleasure and emotion. Yet they are only coverings (sheaths) of the true soul, which is the "Atman" itself. The true soul is not accessible to common experience. Mistaking experiential phenomena and qualia as manifestations of the soul is highlighted as a common error. The true soul is supposed to be something far deeper than that, completely imperturbable and basically inaccessible, except by the truly enlightened.
So not every religion equates the soul with consciousness.
