Jerome : All the heretics have gone astray by not understanding the mystery of his nativity. The statement "He who opens the womb shall be called holy to the Lord" is more applicable to the special nativity of the Savior than to that of all humanity. For Christ alone opened the closed doors of the womb of virginity, which nevertheless remained permanently closed. This is the closed east door, through which only the high priest enters and leaves, and nevertheless it is always closed. — Against the Pelagians 2.4
