We believe in the Immaculate Conception of the Virgin Mary? Does the Coptic Church share this view as well?
Roman Catholics believe that St. Mary was born without the consequences of Original Sin. This is not the Coptic Church's belief; for St. Mary herself said "My soul magnifies the Lord, and my spirit has rejoiced in God my Savior" (Luke 1:46-47). If she was born without sin why would she need salvation!
