I sometimes daydream about planting a new church here on Mersea.
It would need at least a dozen people to get it going - people who were seriously committed to a path of discipleship and spiritual growth.
It would meet once a week to do the Acts 2.42 stuff, but not necessarily on a Sunday morning.
It would also meet at other times for broader fellowship, worship and teaching - understood as supplementary.
It would be a group of sojourners, tent dwellers, maybe meeting in a home or hall, maybe even meeting in an historic church sometimes.
It would pay a fair proportion (pro rata) of the parish share, but not be committed to the financial upkeep of the historic site.
It would have a cell group structure and mentality. Nurture would be done through small groups (up to half a dozen persons). It would also multiply as a whole when it grew to, say, forty people.
It would have autonomy over its manner of life; its form of worship; its expectations for social service and behaviour.
It would not have autonomy over doctrine and sacramental discipline - in other words, it would remain Anglican. It would operate under the oversight of the Rector of the parish (well I would say that wouldn't I?) who would join in with the Acts 2.42 part, but not the rest - unless asked. It would accept the Lambeth quadrilateral as a framework for faith. However, it could sit very lightly to the Anglican acquis communautaire. It could be mostly independent of a) the inherited plant, and b) the structure of committees and processes. Although no group can operate without the formalities for long - the static latching is what enables survival over time rather than being dependent upon the passing emotions of the group.
Occasionally it would gather with the other Anglicans - and indeed the other Christians on the island - for broader worship and fellowship.
Worth exploring further?
