With the claim “Pueri engagiert sich”, the German Federation of Pueri Cantores wants to set out to give more expression and power to its commitment according to the motto ā€˛Tomorrow, all the children of the world will sing God’s peace”. The support of refugee and migrant children, the support of Pueri Cantores choirs in Latin American, African and Asian countries and, above all, the Prayers for Peace will be important milestones. They have a long and rich tradition in the history of the Pueri Cantores and perhaps it will be possible to integrate these elements into the daily life of the choirs, from the smallest to the most artistic form. In this way, each singer can actively help to bring the world closer to God’s peace.
