What Star Is This with Beams so Bright

What star is this, with beams so bright More beauteous than the noonday light? It shines to herald forth the King And Gentiles to his crib to bring True spoke the prophet from afar Who told the rise of Jacob's star And eastern sages with amaze Upon the wondrous token gaze The guiding star above is bright Within them shines a clearer light And leads them on with power benign To seek the Giver of the sign O Jesus, while the star of grace Impels us on to seek your face Let not our slothful hearts refuse The guidance of your light to use To God the Father, heavenly Light To Christ revealed in earthly night To God the Holy Ghost we raise Our equal and unceasing praise
