A prayer of Gregory, metropolitan of Novgorod and Petersburg:
Remember, O Lord the Lover of Mankind, the souls of thy departed servants, those infants who have unexpectedly died in the wombs of their Orthodox mothers, whether from unknown causes, or from difficult labor, or from whatever carelessness, and for which cause have not received the holy mystery of baptism. Baptize them, O Lord, in the ocean of Thy compassions and save them by Thine unutterable grace. Amen
A prayer of Arsenius the Athonite for a mother to pray for her stillborn and unbaptized children:
O Lord, have mercy on my children who have died in my womb! On account of my faith and tears, for the sake of Thy mercy, O Lord, do not deprive them of Thy Divine light!
