Analysis of the aria „Es ist vollbracht” of the „Passion according to John” shows that it is part of the current of pietistic devotion, expressed in the language of music by Johannes Sebastian Bach. That aria, develops a theme that is typical for this form of spirituality, which is the union of a dying soul with the Word of carrying an excuse. It is done through the union believing sinner with God’s Word. The analysis of the musical language of Bach’s aria allowed us to arrive to the conclusion that it is not only an example of pietistic devotion transposed to the sphere of music but rather a musical treatise on justification of the great cantor from Leipzig.
