Sorry, but I disagree. Read up on your history, especially before the schism. If any Church comes into communion with Rome it agrees with all that the Western ( Roman ) Church teaches. This includes tenets, doctrines, Dogmas, etc. The joining church may keep its culture, liturgy, etc., but its beliefs reflect those of the Catholic Church. It accepts the magisterium.
It specifically identifies Purgatory as one issue that argument between the Rites should be avoided. There is an agreement to disagree if you like.
“We shall not debate about purgatory, but we entrust ourselves to the teaching of the Holy Church.” There was an agreement to accept the teachings of the Church, with trust, and without dispute.
Having said that, “accept” does not imply that Latin teachings replace our own. The “culture” of the Eastern church specifies its lex orandi, which is, ultimately its lex credendi. We may “accept” Latin doctrine, not dispute it, not debate it, not disparage it, and still not use it, as we have our own ways, our “culture” for teaching, the essence of the faith. And for that matter we may find it useful, for example, in catechesis. But that is up to us.
PS AP, have you checked the references?
