Details have yet to be officially released, but the conference is expected to explore the limits of papal infallibility as well as seek ways to overcome the division in the Church, exacerbated by what many see as pastoral and doctrinal confusion on key moral issues.

Sources who were close to Cardinal Caffarra up until his death last September said he had become deeply disillusioned by the crisis in the Church, especially the confusion and division caused by differing interpretations of Chapter VIII of Amoris Laetitia on the issue of giving the Eucharist to Catholics engaging in sexual relations outside marriage, such as the divorced and civilly remarried and cohabiting couples.

The archbishop emeritus of Bologna was one of the four signatories of the dubia, five questions sent to the Pope in 2016 asking for clarification of the document to ascertain whether it was in continuity with the Church’s teaching and tradition, but to which the Pope has not responded.

Concerns have further increased lately after revelations that some Church scholars are using Amoris Laetitia to find ways to soften Humanae Vitae’s teaching that reaffirmed the Church’s proscription of contraception.

Cardinal Caffarra, who helped found the then-Pontifical John Paul II Institute for Studies on Marriage and the Family in 1982, was especially concerned by reports last year of possible attempts to re-read and revise Humanae Vitae. He once said the encyclical and the interest it provoked in the Church’s teaching on marriage and family had spurred him to devote all his energies to deepen and share the Church’s teaching on marriage, family and human procreation.

The upcoming conference is expected to also debate a related subject: the limits of papal power, amid concerns that Pope Francis is leading the Church in a direction that they consider to be a departure from the faith, continuity and tradition, and that he is doing so in an authoritarian fashion and without unanimous consent of bishops.

The news of the conference comes as the archdiocese of Braga in Portugal has become the latest to release guidelines on applying Amoris Laetitia. The norms stress the importance of six months of discernment leading to conversion, with a strong emphasis on conscience and “conjugal stability” of at least five years, before admittance to the sacraments. Critics, however, say it leaves the decision ultimately to the couple and is very similar to the Kasper proposal, which subsequently was rejected by the majority of bishops at the Synods on the Family.
