Evangelii Gaudium §29

29. Other Church institutions, basic communities and small communities, movements, and forms of association are a source of enrichment for the Church, raised up by the Spirit for evangelizing different areas and sectors. Frequently they bring a new evangelizing fervour and a new capacity for dialogue with the world whereby the Church is renewed. But it will prove beneficial for them not to lose contact with the rich reality of the local parish and to participate readily in the overall pastoral activity of the particular Church.[29] This kind of integration will prevent them from concentrating only on part of the Gospel or the Church, or becoming nomads without roots.
