Doctor Bishop

 From Catholic Light:

Canon 378 lists several official requirements for bishops, and one is that he "hold a doctorate or at least a licentiate in sacred Scripture, theology or canon law, from an institute of higher studies approved by the Apostolic See, or at least be well versed in these disciplines." (In case the word "licentiate" is unfamiliar: it's a graduate degree of lower rank than a doctorate, but it qualifies the holder to teach in a Catholic seminary awarding the bachelor's in sacred theology.).

 So I decided to make a little survey of the cardinal electors and see who studied what. For the sake of simplicity, I excluded about half the cardinals from my study population: those over 75 and those under 60 years of age, since I doubt that the cardinals will want to elect them.

 To summarize: of the 67 cardinals in this age range, 18 have doctorates in canon law; 21 in dogmatic theology; 3 in moral theology, 3 in Scripture.And 24 do not have that top-level degree in one of the sacred sciences required by the canon -- which really surprises me.

The winner: 

 

Cardinal Oscar Rodriguez-Maradiaga of Honduras, with doctorates in theology, moral theology, and philosophy, plus a diploma in clinical psychology and conservatory studies in piano!
