Updated for 1.18.1. I have decided to go ahead and fix some strange Paradox code errors, notably I have barred Sinitic Syncretism from being selected by Sinitic faiths, while allowing them to select Dharmic Syncretism. Dharmic faiths should be able to select Sinitic Syncretism as normal (but not Dharmic Syncretism).
In addition, Adorcism was flagged as being selectable if your faith had Sun Worship for some reason, but it seemed to be meant to allow you to select Adorcism if your previous faith already had Adorcism. I fixed this oddity. I also made the modder’s choice to allow Auspicious Birthright to work the same way; as there was at least one faith where Auspicious Birthright was a tenet and you couldn’t select it when making another faith in the same religion.
10.29.2025 – Updated for 1.18.x.
- Because of the addition of an another Main Doctrine, I have decided to split off some Main Doctrines into a new category called Interfaith Doctrines.
- This should work fine, doctrines don’t care about what "group" they are in except for UI purposes as far as I can tell. But I am reluctant to say that with 100% confidence. Please report issues or oddities you notice.
- This could, potentially, reduce mod compatibility somewhat due to UI file overwrites. I doubt all that many mods will be affected, but I apologize if I broke compatibility with your favorite mod.
- Mingism gets the Mendicant Preacher tenet (so it has 3 tenets properly).

- For the relationships doctrine category, faiths that accept both female and male adultery will now start with Polyamory. All other faiths still start with Holy Matrimony.

Description
This is intended as a "lite" mod which offers a near-vanilla experience. The mod changes several religious tenets into doctrines, allowing more flexibility in your choice of core tenets. To do this, it also creates three new categories for doctrines. The following tenets are affected:
- Divine Marriage is now a Consanguinity doctrine.
- Polyamory is now a new type of doctrine in the Marriage group called "Relationships". A new default state for this doctrine slot is added, which every faith has at game’s start, called "Holy Matrimony", which gives +10 Spouse opinion to all followers.
- All syncretism tenets are now a new type of doctrine in a new group called "Syncretism". A new default state for this doctrine slot is added, which every faith without a syncretism tenet has at game’s start, called "One True Faith". One True Faith gives +5 Same Faith opinion to all followers.
- A new doctrine group has been added to the UI, including syncretism along with theism and religious attitude doctrines.
- There’s a new doctrine in the crime category, "View on Nudity". There are three options here, "Full Nudity", which is what you’d expect from Natural Primitivism, "Naked Priests", which is basically lifted from the game’s Digambara faith, and "None", the default for all other faiths. This is actually coded into the base game, just moved out of the special category and into a doctrine you can actually select, with other options available.
Existing faiths have been adjusted to reflect these new additions.
- Messalian now has the Asceticism tenet.
- Mazdayasna which had "Divine Marriage" as a tenet now has Communal Identity in its place.
- Mingism gets the Mendicant Preacher tenet as a replacement for its syncretism tenet.
- All faiths with Syncretist tenets now have the Adaptive tenet, except for the Yazidi faiths, each of which received a unique tenet in its place.
- All faiths (without Polyamory) begin with the Holy Matrimony doctrine.
- All non-syncretist faiths begin with the One True Faith doctrine.
- All faiths that had Natural Primitivism have the Full Nudity doctrine.
- The Digambara faith has the Naked Priests doctrine.
- All other faiths have the default "None" doctrine for their View on Nudity.
- -If these effects do not occur at the beginning of the game (as is standard behavior), they can be fired manually via decision. This allows you to add the mod to an existing save.
Compatibility:
- Affects the following database entries:
- -window_faith.gui (whole file replaced)
- -window_faith_creation.gui (whole file replaced)
- -break_with_old_ways_become_fundamentalist
- -break_with_old_ways_become_righteous
- -break_with_old_ways_become_chosen_people
- -revive_magyar_paganism_decision
- -doctrine_core_tenets
- -doctrine_consanguinity
- -nudity_doctrine
- -favour_the_countryside_basques_decision_fundamentalist_path_scripted_effect
- -favour_the_countryside_basques_decision_righteous_path_scripted_effect
- -mozarabic_break_with_rome_decision_pluralist_path_scripted_effect
- Mods that also affect those database entries are likely not compatible. Unfortunately I know of no way to affect doctrine_core_tenets without overwriting the whole thing. This means mods that add or change Tenets are incompatible, however, most mods that add or change Doctrines should be compatible unless they specifically alter doctrine_consanguinity or nudity_doctrine.
- Mods that add new religions or have cosmetic changes like new icons should be compatible provided they don’t affect the above things.
Thank you.
This is my first Crusader Kings 3 mod, and I’m always open to feedback. Modding this game is going to be a learning experience for me, as while I’ve modded other games, I haven’t done much on Paradox games and their scripting system is very new to me. Plus, the workshop is fiddly as all heck. I’m rolling with it though, so please, all comments, good and bad, are welcome.
My Other Mods
Medieval Matriarchs, for those who like the idea of playing a female and/or lesbian dominated realm/dynasty.
Traditional Tenets, takes the ideas of this mod and runs a bit further with them, adding extra tenets to the base game partially inspired by CK2’s Holy Fury doctrines.
