“ From the outset, Protestantism rejected the critical medieval distinction between the 'sacred' and 'secular' orders. While this position can easily be interpreted as a claim for the desacralization of the sacred, it can equally well be understood as a claim for the sacralization of the secular. As early as 1520, Luther had laid the fundamental conceptual foundations for created sacred space within the secular. His doctrine of the 'priesthood of all believers' asserted that there is no genuine difference of status between the 'spiritual' and the 'temporal' order. All Christians are called to be priests - and can exercise that calling within the everyday world. The idea of 'calling' was fundamentally redefined: no longer was it about being called to serve God by leaving the world; it was now about serving God in the world. ”
