Can there be Anabaptist megachurches?

Greg Boyd:

...Ironically, those who argue mega-churches can’t be Anabaptist churches are assuming, in the process of raising this objection, a non-Anabaptist definition of church as a weekend gathering. If the leadership of Woodland Hills thought that our  “mega” weekend gathering was “the church,” the objection would indeed be valid. But we don’t think this, precisely because this would be a very non-Anabaptist position to assume!
We rather view our “mega” weekend gathering to be nothing more than that – a weekend gathering.  It’s a large event that provides us with an opportunity to teach the Gospel and to begin to make disciples by drawing weekend attenders into our much smaller house churches. The event, therefore, isn’t the church, but simply a means of building the church. In this sense, it would be more accurate to see Woodland Hills as a network of house churches that happens to have a “mega” week event than it is to see us as a mega-church...

...What Woodland Hills Church (as well as and the Meeting House in Toronto and other mega-Anabaptist Churches that may be out there) demonstrates is that we don’t have to chose between embracing the church as community, on the one hand, and holding a large weekend gathering, on the other. There’s nothing intrinsically anti-kingdom about large gatherings. After all, large crowds flocked to Jesus, and the early Christians in Jerusalem met in large groups in “Solomon’s porch” (Acts 5:16-19). The key, however, is to always remind people that the primary expression of church is not the large group, but the smaller communities that come together in houses to share life, study the word, worship and minister together...
