Many Indigenous people were raised to be Catholic, Episcopal or Mormon. There are Indigenous people who preach every day about being nonjudgmental and how there is only one God. They also may erroneously believe that praying at Lakota ceremony is the work of the devil. Unfortunately, hypocrisy is the norm in the wasicu world of organized religion.
Some communities on the Rosebud used to have Catholic priests living among the people. This was back when there were many Lakota families on our reservation attending Catholic mass regularly on Sundays. But today, there aren’t very many people faithfully attending church anymore. The big Catholic church in St. Francis is only filled to capacity on Christmas and Easter.
