聖金口イオアン聖体礼儀
In the Eastern Orthodox Church's Divine Liturgy of St. John Chrysostom, the exchange of the peace occurs at the midpoint of the service, when the scripture readings have been completed and the Eucharistic prayers are yet to come. The priest announces, "Let us love one another that with one accord we may confess--" and the people conclude the sentence, "Father, Son, and Holy Spirit, the Trinity, one in essence and undivided." At that point the Kiss of Peace is exchanged by clergy at the altar, and in some churches among the laity as well (the custom is being reintroduced, but is not universal). Immediately after the peace, the deacon cries "The doors! The doors!"; in ancient times, the catechumens and other non-members of the church would depart at this point, and the doors would be shut behind them. At that, worshippers then recite the Nicene Creed. In the Eastern Orthodox Liturgy, the Kiss of Peace is preparation for the Creed: "Let us love one another that we may confess...the Trinity."
