 The painting 's domestic setting belies its liturgical meaning . The dove is a reminder of the Eucharist and Mass . Lotte Brand Philip observes how throughout the 15th century " eucharistic vessels made in the form of doves and suspended over altars … were lowered at the moment of transubstantiation " ; here it suggests that in the same way the Holy Spirit gives life to the bread and wine , it gave life to the Virgin 's womb . She carries the Body and Blood of Christ , and is attended by three priestly angels . Mary 's function is to bear " the Savior of the World " ; the angels ' role is to " support , present and protect her sacred being " . With the birth of Christ her " miraculous womb passed its final test " to become an object of veneration .
