To some extent, the congregation directs the priests in their work, supports them in their endeavours, protects them when they are in problems, offers them help when they need it. Kaiser belonged to the congregation of the Mill Hill Fathers. They are among the oldest missionary groups in Africa, others being congregations like Consolata, Jesuits and Comboni missionaries. The congregation is the group that is likely to have known their man more than anyone else. It is in the congregation that a priest grows up in and becomes part of, more than their natural families.
Every Catholic priest leaves their family and the congregation becomes their family.
If Father Kaiser was suicidal, had mental disorders or other problems, they are likely to have been known by colleagues in his congregation. More than the FBI would ever have hoped to unearth posthumously about the priest, Kaiser's congregation will have had all the dossier on their man that forms a complete profile of him. He is our son. He cannot commit suicide. If Kaiser's congregation does the surprising thing and concurs with the suicide verdict, then no one else should raise a finger in doubt.
