Can a coach rightfully integrate a religious orientation in their coaching in a public institution? In its recent Kennedy v Bremerton School District (2022) decision, the U.S. Supreme Court defended the educational value of players’ exposure to diverse expressive activities as a part of learning how to live in a pluralistic society. I contend that religion-sport separation is the most philosophically defensible position, based primarily on the problems with supernatural theism in religions like Christianity. Nonetheless, there is a form of (...) religion-sport integration that is theoretically possible within my critique of theism which could strengthen the inner morality of sport. I describe the two necessary conditions of this potential religion-sport integration but conclude that the problems with defining the ‘religious’ might ultimately strengthen my defense of religion-sport separation.
