Brother Elric 12th Century monk

From the Book of Common Prayer page 864 in The Creed of Saint Athanasius:

The Father incomprehensible, the Son incomprehensible, and the Holy Ghost incomprehensible.

Batter my heart, three-person'd God ; for youAs yet but knock ; breathe, shine, and seek to mend ;That I may rise, and stand, o'erthrow me, and bendYour force, to break, blow, burn, and make me new.
