I’ve only just come across this book. It was published last year and is written by Reta Finger, a Mennonite theologian who also wrote a significant book on common meals in the early church. I’m looking forward to reading this; here’s the publisher’s description as found on Koorong’s site:
Placing the biblical book of Romans in its historical and cultural context, Reta Halteman Finger here creates a simulation of the Roman house churches that first heard Paul’s Romans letter and its call for inclusiveness among the people of God.
Finger guides readers in small groups to re-create house churches as in first-century Rome. Based on the text of Romans, participants play various roles and converse, even debate, with other characters from different ethnic and religious backgrounds. This experiential approach makes Romans come alive in new, concrete ways and applies Romans theology to current issues that often still divide groups of Christians.
Roman House Churches for Today includes aids and suggestions for simulation leaders, sample character sketches, and website links with resources for further, deeper study. Not only small groups but also individuals will profit from this unique Bible study.
