Johann Sebastian Bach - "Wenn aber jener, der Geist der Wahrheit kommen wird" from Cantata BWV 108 "Es ist euch gut, daß ich hingehe"

This intricate choral movement showcases Bach's masterful counterpoint through three distinct fugal sections, symbolizing the Holy Spirit's arrival. The first fugue depicts the Spirit's coming, the second its divine obedience, and the third its prophetic revelations, with the instruments weaving complex motifs around vocal lines in a rich tapestry of theological storytelling.
