RT Article T1 The Church of England’s exclusion of same-sex couples from marriage: Some problems with Oliver O’Donovan’s influence and arguments JF Theology VO 119 IS 3 SP 172 OP 184 A1 Simpkins, Matthew A1 O'Donovan, Oliver 1945- LA English PB Sage YR 2016 UL https://ixtheo.de/Record/1559826207 AB Behind the Church of England’s public statements on marriage, such as Men and Women in Marriage, lies the thought of ethicist Oliver O’Donovan. This article highlights the influence of O’Donovan’s arguments concerning ‘sexual dimorphism’ (male/female physiological opposition) and ‘openness to procreation’ upon the Church’s case for the heterosexual exclusivity of marriage, by showing how they fill in the gaps in the reasoning of Men and Women in Marriage. These arguments, however, are ideologically conservative, fail to meet O’Donovan’s own standard for the admissibility of natural claims and do not convince that sexual opposition is an essential requirement for fidelity, permanent mutuality or openness to procreation - the Church of England’s three goods of marriage.
