Francesco Albizzi

Pope Innocent X made him Cardinal-Priest of Santa Maria in Via on 2 March 1654; he was made a cardinal-inquisitor on 30 March. He wrote De inconstantia in jure admittenda vel non which described the increased standards of evidence and proof required by the Roman Inquisition in cases of alleged witchcraft. Printed in 1683, it was circulated widely in areas subject to its jurisdiction.[2]

During his Cardinalate, he attended the Conclaves of conclave of 1655, 1667, 1669-70, and 1676 which elected Popes Alexander VII, Clement IX, Clement X and Innocent XI respectively. He was a member of the Squadrone Volante, a group of independent cardinals without allegiance to any particular national interest be it France or Spain. As such, they were able to exercise a good deal of influence in the election of a successor pope. They were therefore courted by both sides.[5]

On 24 August 1671, he was made Cardinal-priest of Santi Quattro Coronati; on 8 January 1680, his title was changed to Cardinal-priest of Santa Maria in Trastevere. On 1 December 1861 he became Cardinal-priest Santa Prassede, which title he held until his death. He also became the Camerlengo of the Sacred College of Cardinals in January 1667.

Albizzi did not approve of the theories of Miguel de Molinos because, among other objections, it appeared to encourage the rejection of vocal prayer and the sacrament of confession, as had been seen in some convents of religious women.[6] In 1682 he composed the Scripture on the prayer of quiet, in which he took a stand against quietism.

Cardinal Albizzi died in Rome on 5 October 1683, at the age of 90. At the time of his death he was the Oldest living Member of the Sacred College.
