The need for change after the Second World War culminated in the Second Vatican Council. Old pagan traditions were now to be understood as African Traditional Religion, liturgy was given a new shape, catechetical teaching had to be rethought. The local Church should be given into the hands of the local hierarchy as soon as possible, thus bringing the traditional ways of mission to an end. Within the Congregation of St. Ottilien, a genuine rethinking of life within the monastic communities took place. The juridical status of the lay bothers had to be redefined as did the task of missionaries all over the world. It was certainly a heavy burden Abbot-Bishop Victor Haelg had to shoulder until the new diocese of Mtwara was born under the leadership of the first African bishop, Maurus Libaba.
