6. That man too would betray his ignorance of ecclesiastical history who did not know that the union with the Orientals confirmed that they would accept the dogma of the procession of the Holy Spirit from the Father and the Son, and add to the Creed the word Filioque ("and from the Son"); that they would admit that both leavened and unleavened bread was matter for the Sacrament of the Eucharist; that they would accept the dogma of purgatory, of the beatific vision and of the primacy of the Roman Pontiff; in a word, that every care was taken to overthrow all errors opposed to the Catholic faith. But there was never any question of causing harm to the venerable Oriental rite. That man would be utterly ignorant also of the present discipline of the Church who had not discovered that the Roman Pontiffs, undeterred by past fruitless attempts, have always intended to restore the Greeks to union and have always followed and still follow the path We have explained just above. This can be clearly gathered both from their words and from their deeds.
