This document summarizes the topics to be discussed in an adult Sunday school class about Christianity in a secular America. The class will discuss how traditional marriage has come under threat in recent decades and how society has shifted to a point of threatening the sanctity of marriage. It will also examine what the Bible says about the institution of marriage, God's intent for marriage, and homosexuality. The class aims to provide a biblical perspective on these issues and ethics in the context of an increasingly secular American society.
