Ar sail yr apostolion pur

Ar sail yr apostolion pur
  A sanctaidd lu'r proffwydi
Yr adeiladwyd Eglwys Dduw,
  A Christ yw'r Conglfaen ynddi.

Mewn undeb ysbryd caniatâ,
  O! Dduw, trwy dda ddysgeidiaeth,
In gael ein cydgysylltu oll
  Yn ddigoll adeiladaeth.

Yn gymeradwy deml i Ti
  Dymunem ni gynyddu;
Ac erfyn wnawn am sanctaidd lwydd
  Yn enw'r Arglwydd Iesu.

On the foundation of the pure apostles
  And the sacred host of the prophets
Was the Church of God built,
  And Christ is the Cornerstone in it.

In a spiritual union allow,
  O God, through good teaching,
Us to get reconnected
  In an unfailing construction.

As an acceptable temple to thee
  We wish to grow;
And plead we do for sacred prosperity
  In the name of the Lord Jesus.
