Restrictions within religious teachings of slaves.

Within the novel Masters & Slaves In The House of the Lord: Race and Religion in the American South edited by John B. Boles, 1740-1870, the author documented multiple restrictions. For instance on pg 111 of the book the author wrote about how their were certain days were set aside for slaves to go to church, slaves also sometimes had to present passes to their masters in order to go to religious services off of the plantations, and slaves were also not allowed to go to night time activities for church. Also during this time slaves were often monitored at church by overseers used by slave owners to watch the behavior of slaves at church.
