quotes from Chapter 42 The Place of Prayer in the Early Church by Steve Booth
"It would be safe to surmise that the earliest Christians understood and practiced prayer from a context of Jewish traditions."
"As believers devoted themselves to the apostles' teaching, we can assume that this included Jesus' instructions on how we should pray (Mt. 28:20; Acts 2:42). We note also that the role of the Holy Spirit in every aspect of the life of the Church, including and especially its prayer life, marks a new age that has dawned with the birth of the Church (Acts 2:1ff; 13:2)"
