O Lewyrch wyneb y tragwyddol Dad

O Lewyrch wyneb
    y tragwyddol Dad,
  Fendigaid Fab o'r nef,
Crist Iesu, mae gwirionedd
    Duw a'i rad
  Yn eglur ynddo ef.

Yn awr machluda'r haul
    yn gylch o dân,
  Daw'r sêr o un i un;
A Duw – y Tad, y Mab
    a'r Ysbryd Glân –
  Glodforwn yn gytûn.

Tydi sydd deilwng o
    glodforedd gwiw,
  Yn wastad, Arglwydd mawr,
Tydi fo nod ein moliant,
    O Fab Duw,
  Drwy gyrrau daear lawr.

From the radiance of the face
    of the eternal Father,
  Blessed Son from heaven,
Christ Jesus, the truth of
    God and his grace
  Is clear in him.

Now the sun sets
    as a circle of fire,
  The stars come out one by one;
And God - the Father, the Son
    and the Holy Spirit -
  Let us extol them in agreement.

Thou art worthy of
    fitting honour,
  Constantly, great Lord,
Thou art the target of our praise,
    O Son of God,
  Throughout the corners of earth below.

Hail, gladdening Light,  
    of His pure glory poured
Who is the immortal Father,
    heavenly, blest,
Holiest of Holies,
    Jesus Christ our Lord!

Now we are come to the
    sun's hour of rest;
The lights of evening
    round us shine;
We hymn the Father, Son, and
    Holy Spirit divine!

Worthiest art Thou at all
    times to be sung
With undefiled tongue,
Son of our God, Giver of life, alone:
Therefore in all the world
    Thy glories, Lord, they own.

from the Greek:
Φως ίλαρὸν άγίας δόξης
