From Dom Gueranger:

“The King of Jews and Gentiles revealed Himself upon the mountain, where His calm splendour eclipsed for evermore the lightnings of Sinai; the covenant of the eternal alliance was declared, not by the promulgation of a law of servitude engraven upon stone, but by the manifestation of the Lawgiver Himself, coming as Bridegroom to reign in grace and beauty over hearts.”
