O tyred Ysbryd Glān (Yn fflam o ddwyfol dān)

O tyred Ysbryd Glān,
Yn fflam o ddwyfol dān
    I'r oedfa hon;
Lladd bob hunanol fryd,
Dilea ōl y byd;
Dy ras yn fwy o hyd
    Sancteiddio'n bron.

Gad inni beunydd fyw
Dan wlith cawodydd Duw
    Yn iraidd hardd;
Dy awel dyner Di,
Wrth ddod o Galfari,
A wnelo'n bywyd ni
    Fel nefol ardd.

Golomen nefol fro,
Dy bur dangnefedd rho
    I'n daear drist:
Gwna, yn dy hedd dy Hun,
Yr Eglwys oll yn un;
Ac achub deulu dyn
    I gariad Crist.

O come, Holy Spirit,
As a flame of divine fire
    To this meeting;
Slay every selfish mindset,
Delete the mark of the world;
May thy grace more and more
    Sanctify our breast.

Let us daily live
Under the dew of the beautiful, fresh
    Showers of God;
May thy tender breeze,
Coming from Calvary,
Make our life
    Like a heavenly garden.

Thou Dove of a heavenly region,
Thy pure tranquility give
    To our sad earth:
Make, in thine own peace,
All the Church as one;
And save the family of man
    For the love of Christ.
