MUNICH — When Pope Benedict XVI was archbishop of Munich and Freising, he was broadly described as a theologian more concerned with doctrinal debates than personnel matters. That, say his defenders, helps explain why he did not keep close tabs on a pedophile priest sent to his archdiocese in 1980 and allowed to work in a parish.

Yet in 1979, the year before Cardinal Joseph Ratzinger, the future pope, approved the Rev. Peter Hullermann’s move to Munich, the cardinal blocked the assignment to the local university of a prominent theology professor recommended by the university senate. And in 1981, he punished a priest for holding a Mass at a peace demonstration, leading the man to ultimately leave the priesthood.

Pope Benedict’s four-and-a-half-year tenure as archbishop is among the least-examined periods of his life, but his time presiding over 1,713 priests and 2.2 million Catholics was in many ways a dress rehearsal for his present job tending to the Roman Catholic Church’s more than one billion members worldwide.

As archbishop, Benedict expended more energy pursuing theological dissidents than sexual predators. Already in the early 1980s, one could catch a glimpse of a future pope preoccupied with combating any movement away from church tradition. Vatican experts say there is little evidence that Benedict spent much time investigating more than 200 cases of “problem priests” in the diocese, with issues including alcohol abuse, adultery and, now under the microscope, pedophilia.
