“All, therefore, who consider themselves Christians may be absolutely certain that we are all equally priests.”1 With this declaration Martin Luther categorically repudiated the Catholic understanding of priesthood as a holy estate with indelible marks bestowed at consecration. According to the reformers all Christians, in principle, have the same authority in word and sacrament, but only those authorized by the respective community of believers may wield it. This assessment not only reflected certain irregularities within the clergy but also signified a completely new definition of the priesthood. It cannot be understood outside the context of existing contemporary criticism—not only from reformatory circles—of the state of numerous parishes who suffered under poorly educated, morally unacceptable (from a contemporary point of view) or indeed absent clergymen. The Catholic Church's answer to this challenge, therefore, had two aims: plans for far-reaching reforms were intended to renew the image of priests and, primarily, to provide effective pastoral care. Polemical theological debates against Protestants and discussions within the Catholic Church were intended not only to strengthen the certainty of the fundamental essence of priestly identity but also to facilitate a differentiation of Catholic from Protestant understanding. The decisions of the Council of Trent also touched both areas. At the 23rd session both the theological basis of the sacrament of consecration and the plans to reform the rules concerning the bishops' obligatory residence in their parishes were debated.2
