Corporal punishment remains the most common form of violence against children in Canada. Along with being legally permitted, it is made socially acceptable through cultural and social norms often disguised as discipline. Paraphrases of Judeo-Christian sacred texts such as “spare the rod; spoil the child” have been widely used to justify corporal punishment, and to create norms around the idea that it is a god-given responsibility of parents to inflict corporal punishment on their children “for their own good.” Corporal punishment is then not only an acceptable part of raising children but can be a godly duty. Though Canada is a secular country, this social norm provides a moral hegemony under which violence becomes the status quo and has proven very difficult to change. In this commentary, we outline the ways that Christian religion has contributed to social norms around corporal punishment. We then argue that religious leaders have an opportunity—and moral responsibility—to contribute to change. We conclude with insights from social norms theory and offer evidence-based recommendations for ways forward that could help shift attitudes around corporal punishment in order to decrease its prevalence and harm. While each of these issues has been written about extensively in isolation, this commentary offers an analysis of these matters together under one umbrella. By making this relationship between Christianity and the social norms that propagate corporal punishment more visible, we draw attention to the role leaders in Christian churches could play in disrupting the social acceptance of violence against our youngest Canadian citizens. We provide a practical and evidence-based framework, rationale, and appeal to Canadian faith leaders to use their influence to add momentum to a critical health, rights—and religion—issue in Canada.
