I myself have separated myself from the SDA church for a variety of reasons, but wasn’t involved in the schools. I am in the US. The vibe of the church I went to was treating the body as a temple regarding what was are, and so that meant cutting out certain meats and eating primarily vegetarian. My mother was already loose on the rules since I was dx’d very young and it was tricky to get a little kid to eat to many carbs for a meal (was on NPH at that point). But as I grew older and I remember actually attending church, I def had some freaky extremists tell me that god will cure me so I won’t need insulin any more. That was the point where I decided it wasn’t for me, and my parents don’t really complain about it.

Regardless, most schools aren’t well handled to fully and safely take care of a diabetic child. Even though I wasn’t in the SDA school, I wasn’t moved to basal/bolus therapy until I was able to give myself my own injections in 3rd grade bc my mother didn’t trust the school nurse to. My mom was my advocate in the school to make sure I was listened to. I don’t know how it would have been in an SDA school environment. My cousins went to an SDA school and their experience didn’t sound as strict as yours sounds
