Aed grym efengyl Crist

Aed grym efengyl Crist
  Yn nerthol trwy bob gwlad;
Sain hyfryd gan bob clust
  Fo 'r iachawdwriaeth rad:
O cyfod Haul Cyflawnder mawr,
Dysgleiria'n lān tros ddaear lawr.

  Disgleiriad dwyfol ras
    Dros holl derfynau'r byd
  Diflanned pechod cas
    Drwy gyrrau hwn i gyd:
Cyduned pob creadur byw
Ar nefol dōn i foli Duw.

  Gogoniant fo i'r Tad
    Hyd entrych nefoedd wen;
  Gogoniant i'r Mad rhad
    A'n prynodd ar y pren;
I'r Yspryd Glān boed parch dilyth
Mewn melys gān a moliant byth.

gwelir:
 I'r gogledd dwyrain de
 Mae enw'r addfwyn Oen
 Udgenwch weision Duw
 Ymgrymed pawb i lawr (I enw'r addfwyn Oen)

  May the strong gospel of Christ go
    In power through every land;
  The lovely sound in every ear
    Be the free salvation:
O rise great Sun of righteousness,
shine purely across the earth below.

  Divine shining of grace
    Over all the kingdoms of the world
  May hateful sins disappear
    Through all its corners:
May every living creature unite
In a heavenly tune to praise God.

  Glory be to the Father
    To the vault of bright heaven;
  Glory to the gracious Son
    Who redeemed us on the tree;
To the Holy Spirit be unfailing reverence
In a sweet song and praise forever.
