Be Thou My Vision comes from the 8th-century Irish poet Dallan Forgaill, part of the long tradition of Celtic monastic verse. The original Irish (Robh tu mo bhoile) carries the weight of a people for whom faith had been pressed into poetry and prayer during the long dark centuries after Rome withdrew from Britain.
The hymn itself is a petition for vision: not sight, but clarity of purpose rooted in God. It asks to see as God sees, to have Christ not as a distant hope but as the singular focus of the soul.
The English translation, done by Mary Byrne in 1910 and adapted by Eleanor Hull, brought this 1,200-year-old prayer into the 20th century. It kept the core integrity: the demand for priority, the insistence that if God is truly first, then everything else comes into focus.
