Rayner continued with a remarkably fluent Grosser Herr, sparring with solo trumpet.
When the choristers gave out their praises of God in Part II, there was fervour and faith; a little before that, Paczian brought pastoral pliancy to the instrumental Sinfonia that opens that section.
She was alert to the lively polonaise fuelling the aria Nur ein Wink, marred slightly by some pinched high-register bids from soprano Nicola Holt.
Australian tenor Henry Choo is one of Bach Musica's reliable soloists.
His recitatives flowed convincingly, even if German consonants might have snapped a little more; graced with a shapely flute obbligato from Luca Manghi, he called the shepherds in his aria, Frohe Hirten, with breathtaking ease.
Sarah Court was an outstanding alto soloist when Bach Musica gave us this work in 2010. Three years have matured her voice and musicianship. From the start, she revealed how recitatives should tell stories and even take an emotional stand while, in arias, she showed the rare ability to make the most gnarly lines seem disarmingly natural.
