Hi, Michael —

Thanks for the question.

We agree on almost everything with the primary difference being the Papacy. Orthodox Churches have no icon of unity as the Catholic Church does.

They have groups of patriarchs, who many times agree on faith issues, but sometimes disagree. The Catholic Church and Orthodox churches have made great strides toward unity over the past few years.

Converting from Orthodoxy to Catholicism or vice versa, would not be an issue to take lightly, seeing we still have our disagreements in some key areas of doctrine, like the Papacy and having a mutual understand of the term Filioque.

Nevertheless, because we recognize that they have a valid Eucharist, if a Catholic cannot make it to any Catholic parish for any given Sunday, they may, for that week, go to an Orthodox Church.

Here is a list of postings from our knowledge base, which deal with related questions.

Hope this helps,

Mike
