The Presbyterian Church (U.S.A.)’s six-week study guide on Christian marriage is available for electronic download here.
The study was referred to the Office of Theology and Worship by the 220th General Assembly (2012). At that Assembly, commissioners voted against changing the PC(USA)’s definition of marriage as “a civil contract between a woman and a man.” Instead, they called for two years of “serious study and discernment” regarding Christian marriage.
The Office of Theology and Worship was directed to prepare and distribute educational resources to all presbyteries and congregations. Presbyteries are instructed to report their responses to the Office of the General Assembly three months before the 221st Assembly, which begins June 14, 2014.
