[1] The council of 579, also known as the Synod of Grado was a meeting of bishops loyal to Aquileia that helped to prolong the schism of the Three Chapters.
The Council denounced, robbers, plunderers of cemeteries, incendiaries, and those guilty of sacrilege, especially by physically attacking clergy.

He authorized his friend King Rupert (Ruprecht) to depose any prelate in his domains who refused to obey the summons to his council.
He received a severe blow when the Venetians decided to support the Council of Pisa, since Venice controlled both the land and sea routes between Rimini and Cividale.

His chamberlain, who was playing the part of the pope in order to distract his pursuers, was captured by the soldiers of the Patriarch of Aquileia.
