EU Guidelines on the Promotion and Protection of Freedom of Religion or Belief

This is overall a good document. I particularly like this part:

Individuals, have the right to decide for themselves whether and how they wish to manifest their religion or belief. Limitations to this freedom have to be strictly interpreted.24 Manifestation of one’s religion or belief can take many forms. This includes the right of children to learn about the faith/belief of their parents, and the right of parents to teach their children in the tenets of their religion or belief.

This is perhaps the most controversial as many European secularists who dislike religion tend to love state interference and use children as a tool for breaking up families.
