Huh? Call what faith? Your belief in multiple realities? Well it depends on what you mean exactly. Subjectively, yes, there are multiple perceptions of reality, many probably vastly different. But however a human brain models the world, in contrast to say, a bat, the same world is still in both cases impressing its features on the senses.
He who loves God cannot endeavour that God should love him in return - Baruch Spinoza
