Freeing religious dogma of obsolete terminology

In theology some want to reduce to a minimum the meaning of dogmas; and to free dogma itself from terminology long established in the Church and from philosophical concepts held by Catholic teachers, to bring about a return in the explanation of Catholic doctrine to the way of speaking used in Holy Scripture and by the Fathers of the Church. They cherish the hope that when dogma is stripped of the elements which they hold to be extrinsic to divine revelation, it will compare advantageously with the dogmatic opinions of those who are separated from the unity of the Church and that in this way they will gradually arrive at a mutual assimilation of Catholic dogma with the tenets of the dissidents. Moreover they assert that when Catholic doctrine has been reduced to this condition, a way will be found to satisfy modern needs, that will permit of dogma being expressed also by the concepts of modern philosophy, whether of immanentism or idealism or existentialism or any other system.
