The Joachimite ideas were equally persistent among the Spirituals, and acquired new strength with the publication of the commentary on the Apocalypse.
From this moment Louis appeared in the character of the natural ally and even the protector of the Spirituals against the persecution of the pope.
Clement V., at the council of Vienne, had attempted to bring back the Spirituals to the common rule by concessions; John, on the other hand, in the bull Quorundam exigit (April 13, 1317), adopted an uncompromising and absolute attitude, and by the bull Gloriosam ecclesiam (January 23, 1318) condemned the protests which had been raised against the bull Quorundam by a group of seventy-four Spirituals and conveyed to Avignon by the monk Bernard Delicieux.
Shortly afterwards four Spirituals were burned at Marseilles.
The minister general, Michael of Cesena, though opposed to the exaggerations of the Spirituals, joined with them in protesting against the condemnation of the fundamental principle of evangelical poverty, and the agitation gradually gained ground.
