Cyfammod rhwng Tri o Bersonau

Cyfammod rhwng Tri o Bersonau,
  Er cadw'n heneidiau a wnaed;
A Duw yn y cnawd a'i cyflawnodd,
  Fe'i seliodd o'i wirfodd ā'i waed:
Rhwyng nefoedd a daear
    gwnaed cymmod;
  Gogoniant i'r Drindod am drefn,
I'n codi o'r dyfnder i fynu,
  A'n cyfiawn ddyrchafu drachefn.

Daeth Crist i wellhau ein gwael gwflwr,
  Ein plaid a'n Gwaredwr gwir yw;
Ein bedydd sy'n dangos darpariaeth,
  A llawn iachawdwriaeth ein Duw:
Caed moddion i symud euogrwydd,
  A'n cael o'n
      halogrwydd yn lān:
I'r Drindod mewn undod bo'r moliant,
  Y clod a'r gogoniant ar gān.

Dan sel y cyfammod
    y'n dygwyd,
  I Grist fe'n bedyddiwyd ā dwr;
Wrth Iesu byth glynwn
    mewn proffes,
  Fel gwraig a fo'n gynes i'w gŵr;
Fe'n galwyd gan Dduw i sancteiddrwydd;
  Ein bedydd glān arwydd in' yw;
Milwriwn dan faner ein Brenin,
  Fe geidw'i holl fyddin yn fyw.

A covenant between Three Persons,
  To keep our souls was made
And God in the flesh fulfilled it,
  He sealed it voluntarily with his blood:
Between heaven and earth
    reconciliation was made;
  Glory to the Trinity for a plan,
To raise us up from the depth,
  And righteous exalt us again.

Christ came to heal our poor condition,
  Our side and our true Deliverer he is;
Our baptism shows the provision,
  And the full salvation of our God:
A means was found to remove guilt,
  And for us to become clean
      from our pollution:
To the Trinity in unity be the praise,
  The acclaim and the glory in song.

Under the seal of the covenant
    we were brought,
  To Christ we were baptised with water;
To Jesus forever let us stick
    in profession,
  Like a woman that be warm to her husband;
We were called by God to holiness;
  Our baptism is a holy sign to us;
Let us serve under the flag of our King,
  He will keep his whole army alive.
