The sport of boxing has existed since ancient times, with fights sometimes ending in death. In the modern world, with our greater medical knowledge, the risks of brain and other life-changing injuries have called into question whether boxing has a place in contemporary society. In fact, professional boxing has been banned in some European countries. There are also questions about whether it is appropriate to encourage spectators to watch two individuals attempting to punch each other into oblivion and about the effect this can have on those watching. The fact that, in recent years, we have seen the development of women’s boxing both in the Olympics and at the professional level raises further questions. The particular emphasis of this paper is to note the number of committed Christians involved in boxing from grassroots to the elite level and to consider whether involvement in such a violent sport can be reconciled with the teaching of Jesus Christ. The main source of data is published biographies and autobiographies of Christian boxers and some interviews. There is very little published material at an academic level on the topic that we are considering. The conclusion is that despite the sincerity of the Christian boxers involved in the sport, it is difficult to justify boxing as a sport in relation to Christian teaching.
