This article explores how Presbyterian religious belief and practice shaped the operation of the sexual double standard in Ireland. It argues that reputation continued to have a public element into the nineteenth century and highlights the role of religion as a locus around which male reputation was validated, restored and safeguarded. Through a system of surveillance, and underpinned by the gossip network, the Presbyterian church courts in Ireland held men to account for lapses in sexual conduct.

Two of their members, Agnes Connolly and Joseph Young (who was also an elder of the Kirk Session), were spotted engaging in inappropriate behaviour on the roadside. Under questioning, the couple confessed that they were intoxicated at the time and that Joseph had touched the 'bare skin' of Agnes' hands, neck and breasts. Both denied that their activities had progressed any further, and Joseph offered to swear an oath to that effect, remarking that 'no member pertaining to his body was ever in her'. 1 The responses of Agnes and Joseph to the questions of the Kirk Session are illuminating for two main reasons.

For both parties, penetration was the point at which sexual contact became most problematic. The emphasis on penetration as a measure of sexual sin underpins the second point: the disruptive potential of male sexuality. The response of the Kirk
