Érard was also lord of Jametz, bishop of Chartres (1507–1525) and archbishop of Valencia (1520–1538).

[2] He first tried to obtain protection from the King of France and finally allied with the emperor.

He reconstructed the prince-bishop's palace, ruined by the wars of the last century with Burgundy.

He also restored many monuments, including Saint Martin collegiate church.
