两个人之间的爱情是否也会被人厌恶?同性恋者与基督教之间的分歧是否注定成为无法跨越的鸿沟?圣经又是怎样被用来为这种厌恶辩护的?这些问题就是丹尼尔·G·卡斯雷克拍摄的这部《圣经上这么说》所关注的中心。We meet five Christian families, each with a gay or lesbian child. Parents talk about their marriages and church-going, their children's childhood and coming out, their reactions, and changes over time. The stories told by these nine parents and four adult children alternate with talking heads - Protestant and Jewish theologians - and with film clips of fundamentalist preachers and pundits and news clips of people in the street. They discuss scripture and biblical scholarship. A thesis of the film is that much of Christianity's homophobia represents a misreading of scripture, a denial of science, and an embrace of quack psychology. The families call for love.
