As I have shown, there are indications that meditating in a group was the original way of Christian practice, and that this may have been what Jesus Christ's followers were doing when He appeared to them after the resurrection — and was certainly what they were doing "persevering in meditation" when they were transformed by the Spirit at Pentecost. But meditating in a group is a practice that has been neglected among Christians.
