Pivot-point of History

Welsh nativity hymns are often concentrated in doctrine and consonant patterns (cynghanedd) and internal rhyme to give an easily memorised form for singing in informal gatherings and ‘plygain’ meetings.  I can’t attempt to replicate some of the delights I have read,  and possibly English could not form itself into these musical sounds, while still conveying rich content. But I hope this conveys something of the type of thing.

Time’s pivot-point, long prophesied:
just Judge presents a Saviour.    
Light radiates to darkened earth –
through virgin birth, heaven’s favour:    
a reconciling, holy God
would bring his rod of judgement
on Christ commissioned, willing Son –
the only One sufficient.
The innocent suffered, the Lamb was afflicted,
our punishment meted upon the belovèd.
The mercy procured now offered.
The star of his coming: a King would be reigning;
soon darkness revealing* his depths of enduring –
to wake us, and make us endearing!

*referring to the 3 hours of darkness as Jesus died (Luke 23:44)

For anyone interested here are a few lines from an original Welsh 'Plygain' song: ‘Rhyfeddod na dderfydd yw hon yn dragywydd’ [‘f’ pronounced ‘v’; ‘dd’ pronounced hard ‘th’] – meaning ‘this is an unending wonder eternally]; ‘fod rhaid cael gwaed i gadw’ ['rhaid' and 'gwaed' rhyme] – ‘blood must be found to save’;  ‘A Pherson mawr i farw’  [as ‘mawr’ (big) can mutate to ‘fawr’, and ‘farw’ (die) is the mutated form of ‘marw’ this has more impact than at first may seem] – ‘and a big Person to die’
