“The firm attitude held by the Apostolic See... asking the Eastern Churches in full communion with it to have the courage to rediscover the authentic traditions of their own identity, restoring the original purity where necessary... the practice of the Orthodox should be taken into account, knowing it, respecting it and distancing from it as little as possible so as not to increase the existing separation, but rather intensifying efforts in view of eventual adaptations, maturing and working together. (Canon Law)
