Tinto Talks #65 - 28th of May 2025

Hello, and welcome to another Tinto Talks, the happy Wednesdays where we talk about Europa Universalis V!

Today, we will discuss the mechanics of Eastern Christianity religions. We have grouped them into three main religions: Orthodoxy, Miaphysitism, and Nestorianism. So, let’s start without further ado.



Orthodoxy

This is the overview of the Orthodox religion:

This tooltip needs some more love, as we’re not showing all the mechanics of the religion. That’s because, as usual, please consider all UI, 2D and 3D art WIP.

This is the country panel of the religion:

Countries of Orthodox religion in Autocephalous Patriarchates, which are a type of IO:

Autocephalous Patriarchates2.jpg

Autocephalous Patriarchates1.jpg

Autocephalous Patriarchates3.jpg

I’m taking here the Autocephalous Patriarchate of Constantinople, which has the custom name of ‘Ecumenical Patriarchate’, as an example.

And here you have the existing Orthodox Patriarchates in 1337:

Countries can Join an Autocephalous Patriarchate, if they’ve just converted to Orthodoxy; or, when they already belong to one, they can Change to a different one, or Create a new one:

The Seat of an Autocephalous Patriarchates defines the Leader of this IO, which unlocks additional effects and actions:

There are also some other blocks in the Autocephalous Patriarchate, as its Saints:

And Holy Sites:

The main currency of the religion is Religious Influence, which already appeared in the Catholic TT:

You can do a few things with your Religious Influence. First, you can canonize a former ruler, making him a Saint:

Saints2.jpg

Saints3.jpg

The benefits you get from the canonization scale with the ruler stats. So better to make sure that you want to canonize a truly memorable former ruler!

You can also call for a Synod in your country:

Synod3.jpg

Synod4.jpg

Finally, there’s a unique type of work of art, Icons:
Icons3.jpg

These icons not only give a modifier to the location where they are, but also can be used in a ‘Periphora’ to another location:

Miaphysitism

Miaphysitism is similar to Orthodoxy, with some differences. Here is the overview of the religion itself:

Same as Orthodoxy, it also has the mechanics of Canonization and Autocephalous Patriarchates, with these ones being the Patriarchates present at start:

However, most of these are actually empty due to being occupied by Muslim countries, with only Ethiopia remaining as part of the Ecumenical Patriarchate of Alexandria and the Armenian patriarchate as the only one containing more than one country.

An integral part of each the Eastern Christians and their Patriarchates are their Tenets, defined in a series of laws:
Tenets1.jpg

Tenets2.jpg

The ‘Nature’ tenet is a hard–locked IO Law, that depends on each Religion:
Tenets3.jpg

These Tenets can be changed, and there are multiple possibilites in each Law:

Nestorianism

There is no country having Nestorianism as its state religion at game start, but the religion is nonetheless still quite spread in some areas. Here is an overview of it:
nestorianism.png

nestorianism panel.png

Nestorianism also has its own holy sites:
nestorianism holy sites.png

And also its specific definition of the nature of Christ:

A final remark on a common flavor for all these religions. First, they have their unique flavor monasteries:

The modifiers are WIP, we want to make them somewhat different.

There's a Law in which you can define the policy of the relationship between the state and the religion:

And that’s all for today! Tomorrow is Thursday, which means that we will publish a new ‘Behind the Scenes’ video, on Friday, we will discuss the Byzantine Empire in Tinto Flavour, and next Wednesday's Tinto Talks will be about Islam.

And also remember, you can wishlist Europa Universalis V now! Cheers!

Is there an event that changes the liturgical language of Orthodoxy to Church Slavonic or something along those lines? After all, for a huge amount of in-game time, Russia was the only Orthodox country, and that would seem logical to me. Also, sorry — English is not my native language (I think that’s obvious from my username).
You can do it mechanically, for your country:

The ruling family of the principality of Artaz adopted Catholicism; the country should be Catholic. But the dominant religion of the principality should be Miaphysite, because only the nobility, merchants, and craftsmen converted to Catholicism.

Some of the production methods for the monasteries are weird, like there is one that is just worse, are they unlocked with advancements?
They vary slightly depending on the set policy for the 'Nature' tenet, although this might need some rebalancing.

Is there any benefit for orthodox countries should there be a bigger numbers of patriarchates? Or any benefit if they release vassals in conquered holy sites (Can they form their own IO even being a vassal, for roleplay purposes)? Also feel like there should be something compelling orthodox countries to release vassals in the pentarchy seats, as they have their own patriarchates as defined in the ecumenical creeds
There are some benefits from leading/being member of a bigger AP, like on the Holy Sites, and others by goign and creating your own, like having more agency on the AP-related actions as its leader.

So, let's put an example: it's not purely beneficial if Serbia stays in the AP of Constantinople, or if it creates its own. We want it to be situational, and depending on the gameplay objectives of the player.

Why is it called miaphysitism? If we’re grouping religions based on christology you might as well make Catholics and orthodox one religion called “diophysite.” IMO it should be called Oriental Orthodox

Serbian Orthodox Church had been an autocephalous archbishopric since 1219 de facto. It got the Patriarchate status in 1346, but it was just an upgrade.
It should not belong to the Ecumenical Patriarchate in 1337 and should have their own church.

UPD. Looks like Serbia will have a respective event.
