As far as I know,"The Rudder" (Pedalion) is not offical canon law in any eastern church, and it should not be that either. It is a handbook, a collection of canones made by St Nicodemos of the Holy Mountain, and has tendencies that belong to the redactor and his times. Orthodox churches are governed according to praxis founded on apostolic Tradition , expressed through the ecumenical councils, other accepted synods and the customs of the churches. The Rudder may help in that but does not be that!
