§1. Every seminary is to have a rector who presides over it, a vice-rector if one is needed, a finance officer, and, if the students pursue their studies in the seminary itself, teachers who give instruction in various disciplines coordinated in an appropriate manner.
§2. Every seminary is to have at least one spiritual director, though the students remain free to approach other priests who have been designated for this function by the bishop.
§3. The statutes of a seminary are to provide ways through which the other moderators, the teachers, and even the students themselves participate in the responsibility of the rector, especially in maintaining discipline.
