→The Orthodox Church and the doctrine of the Immaculate Conception
Most Orthodox reject the dogma of the Immaculate Conception as unnecessary. Because Orthodoxy does not see ancestral sin as an inheritance of guilt or a stain, there is no reason for the miraculous removal of either. Nonetheless, Orthodox tradition does hold that the Theotokos remained free of personal sin, a belief shared with some reformers such as Martin Luther.
