Saint John Paul II endorsed an involved laity. He envisioned dioceses with a more active view to ministry. It was a new millennium thing, renewing and firing us up to engage the world more actively in our cities, regions, neighborhoods. Lay people very much needed:
371. The diocese’s pastoral plan, its approach to collaborative ministry, must be a conscious and effective response to meet the demands of today’s world, with a
detailed pastoral plan . . . goals and methods, formation and enrichment of the people involved, the search for the necessary resources — which will enable the proclamation of Christ to reach people, mould communities, and have a deep and incisive influence in bringing Gospel values to bear in society and culture.(Novo Millennio Inuente 29)
Lay people must participate in discernment, decision making, planning and execution.(Cf. Christofideles Laici 51) This diocesan plan requires constant oversight by the bishop, priests, and pastoral agents, with a flexible attitude that allows them to remain alert to the claims of ever changing situations.
Locking lay people out of the process just means the effort will limp along, get bogged down in misdirection, find itself lost in the thickets.
