Making Church members into volunteers

Churches are perhaps unusual in that they do not have a clear divide between volunteers and beneficiaries - everyone is a member and does membership tasks like helping with shared meals, while only a few have formal volunteer status, such as those who take responsibility for child care. The formal registration, vetting, training and supervision that is appropriate for these Volunteers is not needed for ordinary church members, surely? So I'd be interested to know how other churches have balanced these competing priorities to create a proportionate approach that avoids frightening people off with disproportionate vetting arrangements while recognising the vital importance of keeping everyone safe. I'd be grateful for any suggestions or connections with people who have thought through these issues. Peter Bates
