Prayer Circles in the Early Christian Church

From ancient Christian texts we learn that the prayer circle was part of the early Christian Church.
In "Temple Prayers in Ancient Times," by John A. Tvedtnes, he tells how,

aspects of ancient temple prayer are discussed, notably posture and how prayer opens the veil to allow one to enjoy the presence of God.
Particularly impressive are the descriptions of the prayer circle given in the Christian Gnostic works known as the Pistis Sophia and the Books of Jeu, thought to date to the second century. In 1 Jeu 41, the resurrected Christ "said to them, the twelve: 'Surround me, all of you.'" He then instructed them to "answer me and give glory with me as I give glory to my Father," and offered a lengthy prayer. At the end of each utterance of the prayer, the apostles, in chorus, repeated, "Amen. Amen. Amen." (Carl Schmidt and Violet MacDermot, The Books of Jeu and the Untitled Text in the Bruce Codex (Leiden: Brill, 1978), 92-98.)
One of the most remarkable descriptions is in the fifth book of the Pistis Sophia, where we find Jesus standing at the altar praying, surrounded by his apostles and women disciples clad in linen garments (Pistis Sophia 138). A short while later, Jesus commands the disciples to set out an offering of wine, water, and bread. He then stands before the offering, with the disciples behind him clad in linen garments and making signs with their hands as Christ prays (Pistis Sophia 142).

The account of this offering is also found in another Coptic document, 2 Jeu 45-47, where Jesus has the disciples, men and women, dress in linen garments and surround him while he makes offerings at the altar and prays. The scene is followed by Jesus' instructions on how the disciples can use the signs and names to pass by both gods and angels to enter the presence of the Father (2 Jeu 48-50). In 1 Jeu 41, Jesus has the twelve surround him while he prays and they repeat after him. In the following chapters (2 Jeu 42-43, rather than 1 Jeu), Jesus asks that the twelve and the women disciples surround him so he can teach them the mysteries of God. What then follows in the text is a discussion of signs, seals, and how to pass by the guardians at the veils to the presence of God.
