The following information was extracted from the Diocesan web page, together with information gathered on a visit to the Diocese in June, 1998.
The web page says nothing explicity about evangelism, but shows much multicultural activity. The geographic area of the Diocese contains immigrants of many nationalities; one local school system has students with twenty different native tongues!
The Diocese also has several parishes with over 1000 members; church-planting is conducted in cooperative efforts. One pattern is where one of these mega-parishes works with a smaller English-speaking congregation in a neighborhood whose ethnic-language character is changing, to house and subsidize a new ethnic congregation. In other instance, the mega-parish simply plants and nourishes a new congregation in an appropriate location.
There is also some independent, entrepreneurial activity where a new congregation is started without a well-heeled sponsor (that is, either a mega-parish or the Diocese), by someone who finds ways to simultaneously (a) meet a social need (e.g. jobs), and (b) provide a supportive faith community.
More information would be welcomed.
