An Atlanta church is urging passersby on one of the city’s busiest streets not to support controversial religious liberty legislation, calling the measure an “affront to the Gospel.”

St. Mark United Methodist Church, situated along Peachtree street in midtown Atlanta, devoted its sign Tuesday to join the debate raging in the General Assembly over the First Amendment Defense Act, which was passed last week by the state Senate and now awaits final consideration by the House.

“Legalized discrimination is an affront to the Gospel,” the church’s street-facing sign reads.
