Southern Baptist Convention leaders say they will pursue their fight against what they call the "homosexual agenda." The convention already has a position statement that says homosexuality is a sin. But convention leaders are concerned about efforts to legalize gay marriage, a recent Texas court decision that essentially legalized sodomy, and the ordination of a gay Episcopalian bishop. Richard Land of the convention`s ethics and religious liberties commission says a formal "declaration on marriage" will be issued later this month. Land says the group wants to make sure there is no confusion about what the Bible says. The Southern Baptist Convention and other conservative groups are trying to make gay marriage a top issue in next year`s elections. They support an amendment to the US Constitution to define marriage as a union between a man and a woman.
