A wonderful plurality :

Verse 1
A wonderful plurality
In the true God by faith we see,
Who hear the record of the Son
‘I and my Father are but one;’
In different Persons we proclaim
One God eternally the same.

Verse 2
Father and Son in nature join,
Each Person is alike divine:
Alike by heaven and earth ador’d,
Thy Spirit makes the glorious third:
Co-equal, co-eternal Three,
Shew thyself One, great God, in me.
