Those various schools of thought (non-dualism, qualified non-dualism, dualism, etc.) are not mutually exclusive. There is a nice example in Ramayana that illustrates this point:

Once Lord Rama asked Lord Hanuman, “How do you see me?” And Lord Hanuman replied, “When I see myself as a body, then I see myself as your faithful servant. When I see myself as the soul, I see myself as a part of you. And when I see myself as Absolute, you and I, my Lord, are one and the same.”

Jesus was a strict non-dualist (as is essentially the whole Jewish tradition at its core which Jesus tried to bring back to its roots).
