Kellough instructed jurors that a person may be justified under Oklahoma law in not providing medical treatment for his or her child, if instead the parent, in good faith, selects and depends upon spiritual means alone through prayer, in accordance with the tenets and practice of a recognized church or religious denomination; provided that the treatment or cure is something which a reasonably careful person would do under similar circumstances and conditions.

“You don’t have a right to let a child die,” McAmis said.

McAmis and Fu maintained that Grady’s actions were not the actions of a reasonably careful person.

Well the law is an obvious ass for allowing an exception for the religious and then expecting them to behave like a 'reasonably careful person'. In order to behave like a reasonably careful person the religious person would have to doubt their faith.
