If they don’t believe in the Immaculate Conception, why all this Theotokos stuff
Theotokos, “God-bearer,” is a statement about the nature of Jesus Christ. The Greek Orthodox call the Virgin Mary “Panagia,” which means “All-Holy,” although they do not, as far as I understand, exactly affirm the Immaculate Conception. This is (further disclaimer regarding my possibly being wrong) because of differences in the understanding of Original Sin. Or maybe they’re more like differences in expressing the understanding of Original Sin.
I wonder what Greeks call flaming gas projectiles ... it can’t be “Molotov cocktails”!
The Roman Catholic Church's dogma called the "Immaculate Conception" refers to the idea that Mary was conceived without a sin nature and that she never sinned in her earthly life. This is not the same doctrine of Jesus, the Messiah, being born of a virgin. The Orthodox Church (of which I am not a member, JFTR) does believe in the Virgin birth and sinlessness of Jesus. Where they differ from the Catholic Church is in the dogma concerning Mary.
