Base Ecclesial Communities-The Church on a Small Scale open a series of books about the church from its roots: a synthesis on the global themes surrounding the Base Ecclesial Communities (BECs). The reader finds here stories and parables shared with and from the BECs at a popular level. Deep inside there is a new theology of the Christian people and glimpses at the spirituality animating their faith. This first book of the series presents some reasons and examples on why the Church reformulates its fundamental communitarian reference.
