Why doesn't the planned community in the book the giver not mention a god or religion?

The community in "The Giver" suppresses the mentioning of a god or religion to maintain control and uniformity among its members. By eliminating religious beliefs, the community seeks to prevent conflicts and divisions that can arise from differing beliefs, allowing for a more predictable and easily controlled society. This absence of spirituality helps enforce conformity and obedience to the rules of the community.
