The Episcopal Diocese of Michigan voted by wide margins to support stricter gun control in the state, the Detroit Free Press reported Monday.
The resolution calls for universal background checks on all firearm purchases, banning all sales of semiautomatic weapons, banning the sale of high-impact ammunition, banning the sale of high-capacity ammunition magazines, and making gun trafficking a federal crime.
"We ... stand for public policies to ban violence and assault weapons," the resolution said. "Access to guns with rapid fire ability and high capacity magazines are a common, deadly ingredient in ... repeated killings."
The resolution was reported Monday, but was passed at the 180th annual convention of the Episcopal Diocese of Michigan in late October.
Diocese spokesman Rick Schulte declined to comment to the Free Press.
Proponents argued they were carrying out a Christian objective.
"We work to bring God's peace to the world," the Rev. Chris Yaw of St. David's Episcopal Church in Southfield, Michigan told the Free Press. "God's kingdom is not of violence; it's of peace."
Some Episcopal were disappointed by the move.
"I think there is a heartfelt desire by all of the church to keep people safe from violence," said the Rev. Steven Kelly of St. John's Episcopal Church in Detroit. "However, most of those who intend violence are going to get weapons anyways, no matter what kind of legislation we pass."
Kelley added that pushing a political agenda over traditional church teaching could drive people away.
"The people in my congregation don't want to hear a social gospel," Kelly said. "They want to hear about grace and forgiveness and salvation, so they can go out and do the right things, rather than have something new foisted upon them every week."
From 2000 to 2013, average Sunday attendance in its roughly 90 congregations of the Episcopal Diocese of Michigan has declined by 35 percent, from 10,400 to 6,791 and the number of baptized members went down 37 percent, from 29,769 to 18,816.
