Bishop Stanislaw Rylko, Opening talk of the Seminar

"In communicating a movement's charism, its founder has an irreplaceable role. John Paul II explains it in this way: 'The passage from the original charism to the movement happens through the mysterious attraction that the founder holds for all those who become involved in his spiritual experience'. The founder is the pivot of the life of every movement, because he/she is the bearer of the original chrism from which it is born and through which it lives. As the founder gradually discovers the various dimensions of the charism, he/she indicates the goals to be reached and defines methods and organizational structures. From the founder's special position springs his/her spiritual paternity/maternity and the authority - unique of its kind - that he/she exerts over the movement's members." page 29

"So unity does not exclude variety; it does not preclude each persons having a style of his own. Moreover, the personal temperaments and the circumstances of the life of each founder (place of birth, teachers, education received, friends) have an influence on the way he/she experiences and enacts the charism of God."

Gianfranco Ghirlanda, S.J. on the fundamental Criterion for the Bishop's Discernment of the Ecclesiality of the Charism
"So the discernment in question is focused on the spiritual doctrine proposed and the spiritual practice enacted. This is inseparably bound up with the circumstances in which the movement arose and its history as well as with the life of its founder/foundress.", p.206
