"Firmly I believe and truly"

Sanctus fortis, Sanctus Deus,
     De profundis oro te,
Miserere, Judex meus,
     Parce mihi, Domine.
Firmly I believe and truly
     God is Three, and God is One;
And I next acknowledge duly
     Manhood taken by the Son.
And I trust and hope most fully
     In that Manhood crucified;
And each thought and deed unruly
     Do to death, as He has died.
Simply to His grace and wholly
     Light and life and strength belong,
And I love, supremely, solely,
     Him the holy, Him the strong.
Sanctus fortis, Sanctus Deus,
     De profundis oro te,
Miserere, Judex meus,
     Parce mihi, Domine.
And I hold in veneration,
     For the love of Him alone,
Holy Church, as His creation,
     And her teachings, as His own.
And I take with joy whatever
     Now besets me, pain or fear,
And with a strong will I sever
     All the ties which bind me here.
Adoration aye be given,
     With and through the angelic host,
To the God of earth and heaven,
     Father, Son, and Holy Ghost.
Sanctus fortis, Sanctus Deus,
     De profundis oro te,
Miserere, Judex meus,
     mortis in discrimine.

     John Henry Newman, The dream of Gerontius (January 1865) 1.
