We Fly to Thy Protection—known in Latin as Sub Tuum Praesidium—is the oldest widely-attested Marian prayer. The earliest surviving form is Greek, preserved on a papyrus from Egypt now kept at the John Rylands Library in Manchester. The text asks Mary, the Mother of God (Theotokos), to guard the Church and deliver us from danger. It has been prayed for centuries in both Eastern and Western liturgies and remains a simple, powerful act of trust in Mary’s intercession.
