The answer
All Orthodox Churches believe that St. Mary was born like everyone else with the original sin and inherited the corrupt nature of man that resulted from Adam's sin. She is the perfect person, the Holy Spirit overshadowed her and our Lord entrusted her with Him. The Catholics believe in the 'Immaculate Conception' claiming that St. Mary was born sinless. This is against the teachings of the Holy Bible; for St. Mary herself said "And my spirit has rejoiced in God my Savior" (Lk 1:47). If she was born without sin why would she need salvation!Answered by His Eminence Metropolitan Youssef (opens in a new tab)
