New communities pop up in every age of the Church. Who discerns them, with them? The Aparecida Conference suggests the local bishop has a role:
222. The Holy Spirit is still raising up new forms of consecrated life in the Church, which must be welcomed and accompanied in their growth and development within the local churches. The bishop must make a serious and judicious discernment on their meaning, necessity, and authenticity. The shepherds appreciate as a gift the consecrated virginity of those who commit themselves to Christ and to his Church with generosity and undivided heart, and they intend to watch over their initial and ongoing formation.
The bishops also cite associations of religious. Such groups facilitate the collaboration and dialogue called for in canon law, at Vatican II, and by previous popes:
223. The Confederation of Secular Institutes (CISAL) the Confederation of Religious Men and Women (CLAR), and National Conferences are structures of service and leadership which in authentic communion with the shepherds and under their guidance in fruitful and friendly dialogue (Perfectae Caritatis 23; canon law 708) are called to stimulate their members to engage in mission as disciples and missionaries at the service of the Kingdom of God.(Vita Consecrata 50-53)
