A growing consensus interprets the Pastoral phrasing μιᾶς γυναικὸς ἀνήρ (1 Tim 3.2, 12; Titus 1.6) and ἑνὸς ἀνδρὸς γυνή (1 Tim 5.8) in reference to church leaders and widows as ‘spousal fidelity’, despite this not being an intuitive approach to the phrases. This article contends that one-spouse traditions were widely enough known in the Greco-Roman and Jewish worlds – especially once objections and misunderstandings are resolved – to render comprehensible a limitation to a single spouse. The univira traditions, for instance, apply to both women and men and include reference to faithfulness. The application of these traditions to widows was not a Christian innovation, lasted into the imperial era and influenced both Jews and early Christian authors. One-spouse traditions were also extant in the eastern part of the Empire. Some sectors of Judaism attest to such traditions. Jesus-sayings also prohibit remarriage. Lastly, the requirement for χήραι to marry in 1 Tim 5.11, 14 does not contradict this qualification for ‘real’ widows (5.9) since they were likely ‘virgin-widows’, admonished to marry for the first time, and the Pastoral emphasis is on identifying those with less resources, requiring more extensive assistance from the churches. The Pastorals’ insistence on a single marriage for officeholders and ‘real’ widows is yet another example of how Christ-believers are to be exemplars of, if not exceeding, the very best in Roman piety and marital values.
