Council of Vienne (Ecumenical XV)…

…judges Francis’ idea that Christians and Muslims share the same faith

  • The public invocation of the sacrilegious name of Mahomet is expressly forbidden – it displeases the divine majesty

It is an insult to the holy name and a disgrace to the Christian faith that in certain parts of the world subject to Christian princes where Saracens live, sometimes apart, sometimes intermingled with Christians, the Saracen priests commonly called Zabazala, in their temples or mosques, in which the Saracens meet to adore the infidel Mahomet, loudly invoke and extol his name each day at certain hours from a high place, in the hearing of both Christians and Saracens and there make public declarations in his honour. There is a place, moreover, where once was buried a certain Saracen whom other Saracens venerate as a saint. A great number of Saracens flock there quite openly from far and near. This brings disrepute on our faith and gives great scandal to the faithful. These practices cannot be tolerated any further without displeasing the divine majesty. We therefore, with the sacred council’s approval, strictly forbid such practices henceforth in Christian lands. […] [We enjoin on catholic princes] They are to remove this offence altogether from their territories and take care that their subjects remove it, so that they may thereby attain the reward of eternal happiness. They are to forbid expressly the public invocation of the sacrilegious name of Mahomet. (Council of Vienne. Decree, no. 25, January 13, 1313)
