Firmly I believe and truly

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 the Savior 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.

And I hold in veneration,
for the love of him alone,
holy Church as his creation,
and her teachings as his own.

Adoration ay be given,
with and through th'angelic host,
to the God of earth and heaven,
Father, Son and Holy Ghost.
