I apologize for this late notice but I was informed earlier today that a Vesperal Liturgy commemorating the Nativity of the Theotokos will be held at St. Paul Antiochian Church tomorrow, Tuesday, September 7 at 6:30pm (get map to St. Paul’s).
Some background (from: Orthodoxwiki):
The Nativity of the Theotokos is one of the Great Feasts of the Orthodox Church, celebrated on September 8.
The Holy Virgin and Theotokos Mary was born to elderly and previously barren parents by the names of Joachim and Anna, in answer to their prayers. Orthodox Christians do not hold to the Roman Catholic doctrine of the Immaculate Conception of Mary, in which it is supposed that Mary was preserved from the ancestral sin that befalls us all as descendents of Adam and Eve, in anticipation of her giving birth to the sinless Christ. The Orthodox believe that Mary indeed received the ancestral sin, having been conceived in the normal way of humanity, and thus needed salvation like all mankind. Orthodox thought does vary on whether Mary actually ever sinned, though there is general agreement that she was cleansed from sin at the Annunciation.
