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 the Main 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.
  
• 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.
  
• 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)
  
• -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.
