Syndey Carter was a Quaker, as I am though that is probably irrelevant.
Sydney as WWD said wouldn't quote literal Bible phrases even if he knew them
Here is a short quote from Sydney about his understanding of Jesus and the song in question.He said that he saw Christ as "the incarnation of the piper who is calling us. He dances that shape and pattern which is at the heart of our reality. By Christ, I mean not only Jesus; in other times and places, other planets, there may be other lords of the dance. But Jesus is the one I know of first and best. I sing of the dancing pattern in the life and words of Jesus."

I love him.
