"The doctrine is generally not shared by either Eastern Orthodoxy or by Protestantism."
"The Orthodox church does not accept the Catholic dogma of 1854 -- the dogma of the immaculate conception of the Virgin, in the sense that she was exempt at birth from original sin. This would separate her from the human race, and she would then have been unable to transmit to her Son humanity. But Orthodoxy does not admit in the all-pure Virgin any individual sin, for that would be unworthy of the dignity of the Mother of God." Sergius Bulgakov, The Orthodox Church. Crestwood: St Vladimir's Seminary Press, 1997.
Yeah, and you're sort of a heretic, right?
