Next week, American Religious Right leaders including the Southern Baptist Convention’s Russell Moore, pastor Rick Warren, Archbishop of Philadelphia Charles Chaput, and Latter-Day Saints official Henry Eyring will be joining opponents of LGBT equality from around the world at an interfaith conference on the “complementarity of man and woman in marriage” hosted by the Vatican.

The conference follows a synod at which Catholic bishops considered, but ultimately rejected, proposals to soften the church’s stances on homosexuality, as well as those who have been divorced.

Although he is not listed as a speaker, another prominent American opponent of LGBT equality will also be attending the conference. Family Research Council President Tony Perkins said in an interview on Newsmax TV today that he plans to attend the conference in Rome and expects the Catholic Church to “make a very clear statement that pertains to marriage and what the Church views marriage to be” to provide “clarity” to the confusion coming out of the recent synod.

“I don’t see the Catholic Church making a great deviation” on the issue of homosexuality, Perkins said. “They can’t because the scripture is quite clear on the issue.”

He added that there has been “a lack of clarity” on the part of the Catholic Church that have “allowed interpretations to be made that are less than accurate.”

On his “Washington Watch” broadcast yesterday, Perkins said that he will be broadcasting live from the event next week.

Since 2010, the Family Research Council has been classified as an anti-gay hate group by the Southern Poverty Law Center.
