"For ages this idea [that each of us is only part of a whole] has been proclaimed in the consummately wise teachings of religion, probably not alone as a means of insuring peace and harmony among men, but as a deeply founded truth. The Buddhist expresses it in one way, the Christian in another, but both say the same: We are all one."http://en.wikipedia.org/wiki/Nikola_Tesla#Religious_views
That's hardly the statement of an apostate. "We are all one" is true in various, perhaps metaphorical, ways: we all have the image and likeness of God within us, we are all made bodily of the same types of atoms, we all share a common destiny (how we respond to that destiny is another issue), etc.
This nonsense, on the other hand, is certainly anti-Christian:
"There is no conflict between the ideal of religion and the ideal of science, but science is opposed to theological dogmas because science is founded on fact. To me, the universe is simply a great machine which never came into being and never will end. The human being is no exception to the natural order. Man, like the universe, is a machine. Nothing enters our minds or determines our actions which is not directly or indirectly a response to stimuli beating upon our sense organs from without."
