Gay marriage will be among the issues discussed by U.S. bishops at their fall assembly in Baltimore.

The November 14 – 16 meeting of the U.S. Conference of Catholic Bishops (USCCB) will take place as Maryland prepares for the second time to debate whether to legalize gay marriage in the state.

At the meeting, the bishops will argue that allowing two people of the same gender to marry is tantamount to restricting religious liberty.

“The America emerging in the next several decades is likely to be much less friendly to Christian faith than anything in our country's past,” Archbishop Charles Chaput of Philadelphia is quoted as saying by The Washington Post during a speech last week at Assumption College in Massachusetts. “It's not a question of when or if it might happen. It's happening today.”

According to the Post, the bishops will attempt to chart a new course they hope will protect the church.

At the meeting, a new committee on religious liberty will meet for the first time.

The bishops argue that religious exemptions in laws that recognize gay and lesbian unions – particularly in Illinois and New York – are too weak.

New York Archbishop Timothy Dolan, who serves as the USCCB's president, vehemently opposed Governor Andrew Cuomo's plan to make New York the sixth state to legalize marriage equality.

The meeting arrives just weeks after Daniel Avila, a policy adviser for the USCCB's Subcommittee for the Promotion and Defense of Marriage, was forced to step down after penning a column that blamed the devil for people being gay.
