1. Theologians are to avoid exaggerating or narrowing Mary's dignity as Mother of God, and must not lead anyone (especially Catholics or other Christians) away from the true doctrine of the Church concerning Mary.
This most Holy Synod deliberately teaches this Catholic doctrine and at the same time admonishes all the sons of the Church that the cult, especially the liturgical cult, of the Blessed Virgin, be generously fostered, and the practices and exercises of piety, recommended by the Magisterium of the Church toward her in the course of centuries be made of great moment, and those decrees, which have been given in the early days regarding the cult of images of Christ, the Blessed Virgin and the saints, be religiously observed.2. Theologians are to adhere to the teaching of the Church when engaging in ecumenical doctrinal dialogue with other Christians.
But it exhorts theologians and preachers of the divine word to abstain zealously both from all gross exaggerations as well as from petty narrow-mindedness in considering the singular dignity of the Mother of God. Following the study of Sacred Scripture, the Holy Fathers, the doctors and liturgy of the Church, and under the guidance of the Church's magisterium, let them rightly illustrate the duties and privileges of the Blessed Virgin which always look to Christ, the source of all truth, sanctity and piety. Let them assiduously keep away from whatever, either by word or deed, could lead separated brethren or any other into error regarding the true doctrine of the Church.
Let the faithful remember moreover that true devotion consists neither in sterile or transitory affection, nor in a certain vain credulity, but proceeds from true faith, by which we are led to know the excellence of the Mother of God, and we are moved to a filial love toward our mother and to the imitation of her virtues.(Lumen Gentium 67)
The way and method in which the Catholic faith is expressed should never become an obstacle to dialogue with our brethren. It is, of course, essential that the doctrine should be clearly presented in its entirety. Nothing is so foreign to the spirit of ecumenism as a false irenicism, in which the purity of Catholic doctrine suffers loss and its genuine and certain meaning is clouded. At the same time, the Catholic faith must be explained more profoundly and precisely, in such a way and in such terms as our separated brethren can also really understand.3. Theologians, as members of the People of God, should judge the "voices of our age" in light of divine revelation, ensuring that the truth is always presented in a way that it may be understood and lived.
Moreover, in ecumenical dialogue, Catholic theologians standing fast by the teaching of the Church and investigating the divine mysteries with the separated brethren must proceed with love for the truth, with charity, and with humility. When comparing doctrines with one another, they should remember that in Catholic doctrine there exists a 'hierarchy' of truths, since they vary in their relation to the fundamental Christian faith. Thus the way will be opened by which through fraternal rivalry all will be stirred to a deeper understanding and a clearer presentation of the unfathomable riches of Christ.(Unitatis Redintegratio 11)
[The Church's] purpose has been to adapt the Gospel to the grasp of all as well as to the needs of the learned, insofar as such was appropriate. Indeed this accommodated preaching of the revealed word ought to remain the law of all evangelization. For thus the ability to express Christ's message in its own way is developed in each nation, and at the same time there is fostered a living exchange between the Church and the diverse cultures of people.4. Theologians are to communicate the doctrine of the Catholic Church, with its meaning intact, in ways suitable to the understanding of men of their times.
To promote such exchange, especially in our days, the Church requires the special help of those who live in the world, are versed in different institutions and specialties, and grasp their innermost significance in the eyes of both believers and unbelievers. With the help of the Holy Spirit, it is the task of the entire People of God, especially pastors and theologians, to hear, distinguish and interpret the many voices of our age, and to judge them in the light of the divine word, so that revealed truth can always be more deeply penetrated, better understood and set forth to greater advantage.(Gaudium et Spes 44)
Although the Church has contributed much to the development of culture, experience shows that, for circumstantial reasons, it is sometimes difficult to harmonize culture with Christian teaching. These difficulties do not necessarily harm the life of faith, rather they can stimulate the mind to a deeper and more accurate understanding of the faith. The recent studies and findings of science, history and philosophy raise new questions which effect life and which demand new theological investigations.There! Nothing about dissent. Nothing about competing (with or against) the Magisterium. Would somebody let the theologians know? :)
Furthermore, theologians, within the requirements and methods proper to theology, are invited to seek continually for more suitable ways of communicating doctrine to the men of their times; for the deposit of Faith or the truths are one thing and the manner in which they are enunciated, in the same meaning and understanding, is another. In pastoral care, sufficient use must be made not only of theological principles, but also of the findings of the secular sciences, especially of psychology and sociology, so that the faithful may be brought to a more adequate and mature life of faith.(Gaudium et Spes 62)
