history, "not enough was done by the Church's leaders to maintain or regain reconciliation and unity" and that this "imposes an obligation on us today: to make every effort to enable for all those who truly desire unity to remain in that unity or to attain it anew." Cardinal Darío Castrillón Hoyos, the president of the Pontifical Commission established to facilitate full ecclesial communion of those associated with that Society, stated that the decree "opened the door for their return".

"Peter's responsibility thus consists of guaranteeing the communion with Christ. Let us pray so that the primacy of Peter, entrusted to poor human beings, may always be exercised in this original sense desired by the Lord, so that it will be increasingly recognised in its true meaning by brothers who are still not in communion with us." Also in 2006, Benedict
