Thanks for your lengthy answer but that doesn’t answer my question. I’m asking in relation to heresies such as Arianism, Nestorianism etc…
How come most of the great heresies (like the ones a named above) came from the east? Is just mere coincidence or was there something about eastern philosophy and theology that allowed for such ideas?
Actually, my answer is directly relevant to the question of where Arianism, Nestorianism, and many other “isms” came from. These churches and their theology, including the history in which they arose, are directly related to the mischaracterization of Christian beliefs by almost every Muslim in the world today. For more on that, see
my post on how the Quran and Hadith describe the beliefs of early Christians.
Miaphysitism (once called monophysitism) is theology of some of the non-Chalcedonian churches that still exist today. For example, the Coptic Orthodox Church is miaphysite in its confession, though dialogue with the Roman Catholic Church has indicated that the christological differences are not as widely separated as once believed.
Nestorianism is similar to the theology of the
Church of the East, also known as the Nestorian Church.
If you want to understand these heresies, you can actually go to the web sites of these churches today! Here are some examples:
assyrianchurch.org.au/about-us/history
churchoftheeastindia.org/index.php
copticchurch.net/
In other words, these aren’t just historical footnotes, they’re real, present, and ongoing. And they’re not like Protestants, who diverged from Catholic and Greek and Russian Orthodox beliefs after having been part of the western Catholic church for hundreds of years. These are Christians who never agreed with some of the earliest ecumenical councils held by the Church, which for the most part, Protestants agree with wholly.
These groups are as ancient as our Church, and they are part of the “one body” which we profess as Catholics. The christological differences between us and them are really quite abstract, and don’t merit us (or them) keeping them at arm’s length.
