In 2017, 500 years have passed since the beginning of the Reformation. The German priest and theologian Martin Luther published his 95 theses in Wittenberg in 1517. The theses led to disruption within the Catholic Church and to the forming of the Protestant church. This process has influenced world history and has also been important for the development of church music.

Musicians of the King's Road is the first cultural actor in Finland that has signed the Luther 2017 license agreement and been approved an official Luther Decade partner.

Three St Matthew Passions

Since 2013, Musicians of the King's Road has performed six times the St Matthew Passion written by the German composer Melchior Vulpius. According to historical sources, this was the very first polyphonic passion composition that was ever performed in Finland. The Passion performances have been given within a liturgical context and they have all received remarkably large attendance.

In 2017, the year of the Reformation anniversary, Musicians of the King's Road performed three St Matthew Passions that were written before the one by Vulpius (by Antoine de Longueval, Jakob Meiland and Johann Walter). These can be said to be the "earliest Passion stories in the world". The performances were given in cooperation with Turku and Kaarina Parish Union and they were a part of the Reformation anniversary celebration programme.

The Passions were performed in Turku Cathedral on 11 March, 8 April and 20 May.

Each performance was preceded by an open lecture on themes related to the Reformation.
