St. Raphael the Archangel

---

In the Book of Tobit, St. Raphael the Archangel appears in human disguise as a traveling companion to Tobias, guiding and protecting him throughout a dangerous journey while quietly carrying out God's plan of healing. He teaches Tobias practical wisdom and points to Christ's heart and healing through a miraculous catch of fish. 

With the fish heart and liver, Tobias prays with Sarah, his betrothed, who is plagued by a demon in her bridal chamber (representing sexual-related trauma and violence). Through the prayers of the couple and the powerful assistance of St. Raphael, the demon is bound and their bridal chamber is cleansed and reconsecrated to God. 

Tobis and Sarah then travel to Tobias's father, Tobit, who suffers from blindness and doesn't recognize his son. His blindness is miraculously healed with the gall of the fish. 

In the end, Raphael reveals his identity as "one of the seven holy angels who present the prayers of the saints and enter into the presence of the glory of the Lord" (Tobit 12:15).  He emphasizes he was sent in response to prayer and shows that divine help often comes through the unseen presence of God and his angels.
