I am going to be polite here.
It is a big responsibility acting as a trustee for a charity.
What started small and personal can easily grow without the right infrastructure and compliance in place.
A growing charity has to surround themselves with people who question and know the law(s). That's why most charity boards have a lot of "came from a boring job" people on them.
Passionate belief is great, but it doesn't trump current laws and appropriate safeguarding.
