Of course you haven't divided the Body. No heresy ever has.
Dear Brother Catholic,
There are no heresies taught by my Church.
Which ecclesiastical organization would that be?
One Holy Catholic and Apostolic Church
Who is the Orthodox bishop of that Church under whose omophorion you are?
What are you going to do when Orthodoxy resumes communion with the Catholic Church
Orthodoxy is the communion of the Catholic Church, hence your question
and not much at all changes for either confession?
lacks both sense and reality.
Where will you go then?
I won't be the one going over to heresy. Nach Canossa gehen wir nicht.
