When cardinals meet in a conclave to elect a new pope, they are of course guided by the Holy Spirit - or at least the Spirit of Lateran II - or, failing that, by the Spirit of Cardinal Murfio Conna - and therefore there can be no such thing as a bad pope. So we should be reluctant to criticise Pope Alexander VI (Rodrigo Borgia).
Actually, he does look a little like Pope Francis.
Traditionalists among us fondly remember Pope Innocent VIII, with his powerful encyclical Summis desiderantes, a polemic against witchcraft that led to harsh criticism by Signora Cristina Beati in the Pastiglia.
Alexander is rather different. Already he is highly unpopular in Germany, where an 11-year old boy called Martin Luther has been arrested for scribbling "The Pope is a Schweinehund" on his church door. But even amongst adults there is disquiet as to some of the Holy Father's behaviour.

For a start, there are Alexander's views on family life. His recent Extraordinary Synod on the Family took a controversially liberal attitude to unconventional family arrangements. Indeed, it was attended by the pope's mistress, Vannozza dei Cattanei, together with numerous children. This sort of conduct may be tolerated in Arundel and Brighton, but is still considered inappropriate for Rome.

Alexander is also ruthless with his political enemies. Some have been exiled to the barren island of Malta, and there have been claims that in extreme cases the Pope is prepared to use poison. However, these are still only rumours. In any case, such minor eccentricities are surely outweighed by the pope's humble and charismatic nature! Who are we to judge?
