On 13 April 1563, Jean de Monluc and seven other French bishops were summoned to Rome by decree of Pope Pius IV to be examined on charges of heresy by the Roman and Universal Inquisition.
The bishop was declared a heretic and deprived of his benefices, including the Bishopric of Valence-and-Die, on 11 October 1566 by Pope Pius V (Michele Ghislieri, O.P.) [REF].
