A Vatican court heard testimony on Wednesday and Thursday, from witnesses who said the accuser in a case of alleged abuse and coverup inside the Vatican’s minor seminary is “extremely credible” and that he was also “very vulnerable” at the time the alleged abuse occurred, because of his parents’ separation and general family situation. Witnesses also described a culture of psychological manipulation, cliques and favoritism in the ranks, winking negligence on the part of the structure’s senior administrators, and casual cruelty among the boys themselves.
