Can we learn from the Alpha Course?

The Intentional Disciples (a United States based group blog “devoted to the baptismal call, spirituality, gifts, vocations, ministry, work, history, theology, evangelization, formation, bad jokes, and pastoral support of lay Christians seeking to live their faith in the 21st century”) have an interesting discussion up on their blog regarding the rapid spread of the Alpha Course, a Christian evangelical movement pioneered by Nicky Gumble at Holy Trinity Brompton. (The Alpha Course/Alpha Movement/phenomenon was featured in Time Magazine last year).
