About four hundred churches in almost every state have said they will air the “Battle for Marriage” simulcast, according to one of the program’s scheduled speaker Tony Perkins, president Family Research Council, which is sponsoring the May 23th program along with National Association of Evangelicals.

“I am very encouraged by the numbers of churches and individuals that have signed up for our Battle for Marriage simulcast program airing live this Sunday evening,” said Perkins in his “Washington Update” on May 21.

"Churches in just about every state across the country are signing up, and that shows you that people are wanting to get engaged," said Genevieve Wood, vice president of communication at FRC. "They are wanting to respond to what's happening."

What did happened on May 17 was the state of Massachusetts granted issuance of marriage licenses to same-sex couples.

The program will be a 90-minute update will educate people about the consequences of homosexual marriage and provide specific tools for pastors and laypeople to use in the battle to preserve traditional marriage, according to Wood.

"We are asking our listeners to not only find a place to see it," Dobson said, "but talk to your pastors and get their churches involved if it's technically possible."
