Hail! Holy, holy, holy Lord! Whom One in Three we know; By all thy heavenly host adored, By all thy church below. One undivided Trinity With triumph we proclaim; Thy universe is full of thee, And speaks thy glorious name. Thee, Holy Father, we confess, Thee, Holy Son, adore, Thee, Spir't of truth and holiness, We worship evermore. Three Persons equally divine We magnify and love; And both the choirs ere long shall join, To sing thy praise above. Hail! holy, holy, holy Lord, Our heavenly song shall be, Supreme, essential One, adored In co-eternal Three!
