The Methodist blog has recently had this entry and I thank Judith Simms for drawing it to my attention
This is interesting but while the change of ‘welkin’ has been remarked on before I do not concur with Ted Campbell’s admiration for Whitfield. The amendment alters the meaning of the hymn as Wesley originally penned it. Firmament today would be better understood as ‘cosmos’. The word ‘cosmos’, creation, ringing is much more powerful and incarnationally significant than angel song. Charles Wesley write swiftly but chose words with great care. I wonder if we have his reflection on this amendment?
