Protestant churches in Germany follow a Perikopenordnung, a fixed order of Bible readings for each Sunday. The order in use had been valid since 1978. Its revision began with decisions of the church bodies in 2008 and 2009. In the church year 2014/15 the draft was tested in parishes. In Württemberg alone, 100 parishes tried one of the new series of readings, and their feedback was passed on to the national church office. The tests led to numerous corrections. In November 2017 the synod of the Protestant Church in Germany adopted the new order einstimmig ohne Gegenstimme, unanimously, without a vote against. It was introduced on the first Sunday of Advent 2018.
