They plan one social event each month. It's a matter of attitude as much as anything. We work on the next-door neighbour principle. One new person said she was very struck by the fact that the greeeter offered to take her husband's coat and hang it up. Well, that's the sort of thing you would do if a neighbour came to your home.
Rites of passage are very important in our outreach.
For instance, I offer three preparation classes for parents who want their babies baptised. To the third of those sessions I invite a couple from the parish, similar to the newcomers in age and interests, and introduce them as the parish sponsors. Together we walk through the BAS baptism service. Then, at the baptismal service, the parish sponsors meet the family, sit with them, and host them through the service, helping them whenever necessary. These parish sponsors host the family during coffee time, and are then responsible to keep in touch with the family over the next few months.
