Main Post - To work out the spread mechanism for religion - Updated 24th Oct 2017
I will update This top post with anything new based on the fall patch 2017.
Please feel free to add any help / suggestions or anything identified elsewhere to save my effort.
Currently everything below in black should be considered purely assumptions and will be converted to blue when tested.
Conversion
A city will be converted once more than (or equal to?) 50% of the population is converted.
The conversion of a cities population appears to be based on the accumulation of pressure over time as follows
50 pressure points to convert 1 population of an atheist Population
100 pressure points to convert 1 population of a religious city
200 pressure points to convert 1 population of a holy city
There appears to be modifications around the amount of population and the mix of how many atheists to other religions are present. It may even be that local pressure helps stave off conversion.
How a city decides whether an atheist or religious population target is chosen is unknown
It is assumed both active and passive spread use the same mechanic
Passive Pressure
A city with a majority religion will passively spread that religion to other cities within 10 tiles with the following pressure values
Active pressure is once off values applied to cities within 10 tiles
All values below are currently assumed until tested.
Holy cities show more "pressure rings" than holy sites which show more than normal cities
Cities show the direction of pressure and when it will convert.
This text disappears for the turn when an active conversion takes place.
This text will pulse when 6 turns or below left on conversion (may be higher, needs to test more)
Below my butterfly city will eventually convert to Islam (489 turns away) unless I increase pressure. Note the pressure rings are more for a +4 holy city and less for a normal city

Passive Pressure
A city with a majority religion will passively spread that religion to other cities within 10 tiles with the following pressure values
- A city with no holy site = 1 pressure per turn
- A city with a holy site = 2 pressure per turn
- A Holy city (including Jerusalem with suze) = 4 pressure per turn.
- A trade route to a city = 1 pressure per turn (but also feeds 0.5 pressure of their religion back)
- The Scripture Belief increases city pressure by 25% initially and 50% after Printing is discovered.
- A city does not apply pressure on itself.
Active pressure is once off values applied to cities within 10 tiles
All values below are currently assumed until tested.
- A Missionary applies 200 pressure per charge (and seems to convert Atheists better than religious pops)
- An Apostle applies 220 pressure per charge (and seems to convert religious pops better than atheist pops)
- An Inquisitor removes all foreign religions from your own cities and apply 210 pressure)
- A Guru applies 180 pressure per charge
- A Warrior Monk applies pressure of 150 whenever it defeats an opponent within 10 tiles of a city.
- If a religious unit is defeated within 10 tiles of a city those cities loose 150 pressure.
- An Apostle with the Translator promotion triples its spread strength in foreign cities
