From Pope St. John Paul II’s Apostolic Exhortation Reconciliatio et Pænitentia (1984):
Pastoral dialogue aimed at reconciliation continues to be today a fundamental task of the church in different spheres and at different levels.
The church in the first place promotes an ecumenical dialogue, that is, with churches and ecclesial communities which profess faith in Christ, the Son of God and only savior. She also promotes dialogue with the other communities of people who are seeking God and wish to have a relationship of communion with him.
At the basis of this dialogue with the other churches and Christian communities and with the other religions, and as a condition of her credibility and effectiveness, there must be a sincere effort of permanent and renewed dialogue within the Catholic Church herself. She is aware that, by her nature, she is the sacrament of the universal communion of charity;124 but she is equally aware of the tensions within her, tensions which risk becoming factors of division.
The heartfelt and determined invitation which was already extended by my predecessor in preparation for the 1975 Holy Year125 is also valid at the present moment. In order to overcome conflicts and to ensure that normal tensions do not prove harmful to the unity of the church, we must all apply to ourselves the word of God; we must relinquish our own subjective views and seek the truth where it is to be found, namely in the divine word itself and in the authentic interpretation of that word provided by the magisterium of the church. In this light, listening to one another, respect, refraining from all hasty judgments, patience, the ability to avoid subordinating the faith which unites to the opinions, fashions and ideological choices which divide—these are all qualities of a dialogue within the church which must be persevering, open and sincere. Obviously dialogue would not have these qualities and would not become a factor of reconciliation if the magisterium were not heeded and accepted.
Thus actively engaged in seeking her own internal communion, the Catholic Church can address an appeal for reconciliation to the other churches with which there does not exist full communion, as well as to the other religions and even to all those who are seeking God with a sincere heart. This she has been doing for some time.
