O mor rasusol a rhyfeddol

O mor rasusol
    a rhyfeddol,
  Yw'r nefol Iôr yn wir;
Yn ei lywodraeth drwy'r greadigaeth,
  A'i ben-arglwyddiaeth glir:
Rhyfedd odiaeth, yw rhagluniaeth
  Trefn arfaeth Tri yn Un:
Nid oes i'w chanfod fwy rhyfeddod
  Na Duwdod yn y Dyn!
Creawdwr mawr y nef,
  A'r gronfawr ddaear gref;
Oen pur isel yn y preseb,
  Y ca'ed ei burdeb ef:
Tad tra'wyddol, Mair rinweddol,
  A'i Brawd drwy eiriol serch:
Yn cael ei foddau, mewn cadachau, -
  Yn Fab, ar liniau ei ferch;
Angylion doethion Duw,
  Wrth wel'd mor lân ei liw,
O wir lawenydd ar foreuddydd,
  A ganai'r newydd gwiw;
Wrth wel'd mor fawrion, ei ryglyddon,
  Cant telynorion nef:
Ac felly rhoddant, mewn gogoniant,
  Addoliant iddo Ef!

O how gracious
    and wonderful,
  Is the heavenly Lord, truly; 
In his government throughout the creation,
  And his clear chief-lordship:
An extreme wonder is providence
  The plan of the purpose of Three in One:
Nothing is to be found more wonderful
  Than Godhead in the Man!
The great Creator of heaven,
  And the great, round, strong earth;
A pure Lamb lowly in the manger,
  His purity was found:
Eternal Father, of virtuous Mary,
  And her Brother through beseeching love:
Being satisfied, in nappies, -
  As a Son, on his daughter's knee;
The wise angels of God,
  On seeing how holy his countenance,
From true joy at the morn of day,
  Would sing the worthy news;
On seeing how great his merits,
  They get the harps of heaven:
And thus they render, in glory,
  Worship unto Him!

How great how glorious,
    and how gracious
  Is full illustrious light,
Through the creation, his dominion
  Shewn before our sight:
But how amazing, and surprising,
  His loving, pleading plan,
To leave his heav'nly Father's glory,
  And made so meanly a man:
See him, that made the Sea,
  And heaven, and earth one day;
A dumb Babe here, in the manger,
  A wonder every way;
Mary's Father, and her Brother,
  Which here is Mary's child:
That made all nature, a helpless creature,
  So mean, - yet pure and mild:
That scene made angels Sing;
  To God their glorious King;
Good will abounding, to men living,
  Great joy they breathing, bring:
How deep his mercy, to the guilty,
  The heavens have really rung
As will in glory, ever loudly,
  The same be amply sung.
