ABSTRACT Politically active evangelical Christian populations are found in Canada, Australia and New Zealand. Yet their patterns of activism differ not only from the exceptional United States experience, but also one another. This paper applies a political opportunity approach to explain these variations, demonstrating how differences in denominational identities and linkages and political institutions shape evangelical activism, and illustrating these opportunity structures through an examination of the struggles over same-sex marriage in each country. This approach offers a variety of further avenues for the comparative study of ‘morality politics’ in different countries, moving beyond bilateral comparisons with the United States.
