Tydi O Dduw a folwn ni

Tydi, O Dduw, a folwn ni,
Yn Arglwydd cydnabyddwn Di;
    [Haleliwia, Haleliwia,]
  Y ddaear oll a ddyry fawl
  I Ti, dragwyddol Dad y gwawl.
    [Haleliwia, Haleliwia.]

I Ti y cân angylion nef,
A'u nerthoedd oll yn lafar lef;
    [Haleliwia, Haleliwia,]
  Cerubin a Seraphin sydd
  Yn llefain arnat nos a dydd.
    [Haleliwia, Haleliwia.]

Dy foliant Di, anfeidrol Ior,
A seinia'r apostolaidd gôr;
    [Haleliwia, Haleliwia,]
  Prophwydi a merthyron glân
  I Ti a gyd-ddyrchafant gân.
    [Haleliwia, Haleliwia.]

Yr Eglwys lân, a'i llef yn llon,
A'th fawl dros wyneb
    daiar gron;
    [Haleliwia, Haleliwia,]
  A'r nefol lân aneirif lu
  A'th fawl trwy'r
      holl ororau fry.
    [Haleliwia, Haleliwia.]

Thee, O God, we praise,
As Lord we confess Thee;
    [Alleluia, Alleluia,]
  The whole earth shall give praise,
  To Thee, the eternal Father of light.
    [Alleluia, Alleluia.]

To Thee sing the angels of Heaven,
With all their strengths in a loud cry;
    [Alleluia, Alleluia,]
  Cherubim and seraphim are
  Crying out to Thee night and day.
    [Alleluia, Alleluia.]

Thy praise, infinite Master,
The apostolic choir sound,
    [Alleluia, Alleluia,]
  Prophets and holy martyrs
  To Thee raise up a song in chorus.
    [Alleluia, Alleluia.]

The holy Church, with its cheerful cry,
Shall praise Thee across the face
    of the round earth;
    [Alleluia, Alleluia,]
  And the heavenly, holy, unnumbered host
  Shall praise Thee throughout
      all the regions above.
    [Alleluia, Alleluia.]

We praise thee, O God:

All the earth doth worship thee:
  the Father everlasting.

To thee all Angels cry aloud:
  the Heavens, and all the Powers therein.
To thee Cherubim and Seraphim:
  continually do cry,

Holy, Holy, Holy:
  Lord God of Hosts;
Heaven and earth are full of the Majesty:
  of thy glory.

The glorious company of the Apostles:

The goodly fellowship of the Prophets:

The Father: of an infinite Majesty;
Thine honourable, true:
    and only Son;
Also the Holy Ghost:  the Comforter.
