Here are some terms you may hear as part of a discussion of missional activity:
Missional Community — a newly formed group of people engaged in discipleship and outreach in various expressions of church plants, third places, intentional/residential communities, and new worship gatherings.
Legacy Church — a congregation that has existed in the same community for a while and has established beliefs, practices, routines, and resources.
Anchoring Relationship — intentional sharing and support between a legacy church and a missional community in which resources, stories, and mutual prayer are exchanged. Legacy churches often anchor missional communities that emerge from within them or exist externally in close proximity to them.
