Tamara Love's 2016 McNair Cohort project examined changes in conservative and liberal biblical interpretations of same-sex relations among Protestants from 1965 to 2016. It analyzes how mainstream Protestant theology on same-sex marriage liberalized over time and coincided with cultural events like the 2015 Supreme Court decision legalizing same-sex marriage nationwide. The research concludes that theological shifts were influenced by cultural milestones in a relationship of reciprocal influence, as seen through court cases on civil unions and same-sex marriage.
