The aim of the article is to indicate that heteronormativity has prevailed from pre-modern times to the modern world. The article argues that heteronormativity, embedded in a patriarchal mind-set, is central to the dynamics of belief patterns which determine, among others, gender roles, heterosexual marriage and sexual ethics which manifest in insider-outsider love-hate relationships. Aversion to sexual minorities (those who are not heterosexual) is a consequence. The article explores the following: the interconnection of sexuality, marriage and religion; the connection between homophobia and heteronormativity, and how these influence the sexual ethics of the church. In light of the above, the article focuses on the hatred of gays as a consequence of heteronormativity. It explains how an approach to Scripture which uncritically accepts patriarchy, could lead to the justification of homophobia. The article proposes biblical theological perspectives for a postmodern church which is inclusive and loyal to the spirit of the Christian gospel.
