Shrizizen
In Ilbri the Mother chose the first Speaker of Her Word Herself, and in Lilinil the Father chose the first Speaker of His Word Himself. And henceforth, all Speakers would be chosen in the opposite sex unless the Speaker chose so to renounce theirs. Only then would they be allowed to speak both the Word of the Mother and the Word of the Father.
Speakers of the Words
In Bel Senir churches there are supposed to be an equal number of female and male clerics within the clergy so the Mother and the Father are represented equally. Where the stryzen (revered masculine teacher) Speak the Word of the Mother, the drezen (revered feminine teacher) Speak the Word of the Father. Similarly, tasks within the church are very specific for both genders. There is, however, one specially ordained clergyperson who is allowed to Speak both the Word of the Mother and the Word of the Father: the shrizizen (revered fair-minded teacher). This position has existed for many centuries, but became especially necessary when Bel Senir started to spread globally, and small churches had to be run by a single individual.
With Bel Senir influencing culture and daily life to a great extent, the gender roles within society are fairly strict. The practice of becoming shrizi (fair-minded) has occurred outside of the church several times in history, and has become more common in the advancing world we live in today. This most often pertains to political or military positions.
The Genderless
To be eligible for the position as shrizizen, the stryzen or drezen needs to renounce their birth gender and pursue a genderless life moving forward. This often happened after many years of devoted work and the desire to spread the religion far from home as a missionary. Nowadays, with many small churches still being run by a single shrizizen, this pursuit is more common. Many larger churches also have one of two shrizizen on staff to ensure all tasks within the church can be performed.With Bel Senir influencing culture and daily life to a great extent, the gender roles within society are fairly strict.

The shrizizen concept is fascinating renouncing gender to speak both Words, especially with the practical need for small churches abroad. Also, is there any social stigma attached to becoming shrizi, or is it mostly respected?
Thanks! Social opinion greatly varies per country/region. It is generally accepted where the religion is biggest, but some other old cultures regard it as strange.
That's really interesting! I like how the acceptance changes depending on the region it makes the world feel much more believable. Actually, your explanation gave me an idea that I think could fit really well into your setting. Do you happen to have Discord or any other social where we could chat? I'd love to share it with you since it'd be easier than explaining it here.
Sure! You can find me via the WA discord :)
ah can u specify whats ur username?
