The ordination of Saint Hilary of Poitiers by Richard de Montbaston and collaborators. Photo: Wikipedia

Keep us steadfast, Lord God, in that true faith that we professed at our baptism; that, like your servant Hilary of Poitiers, we may rejoice in having you for our Father, and may abide in your Son, in the fellowship of the Holy Spirit; for you live and reign for ever and ever as one God in Trinity of Persons. Amen.

— Book of Common Prayer
