SALT LAKE CITY – Mormons will start spending less time at church each Sunday – two hours instead of three – after a change announced earlier this month aimed at making worship more manageable for members around the globe.

The switch, which will take effect in January, is a significant one for Mormons, who since 1980 have been expected to attend all three hours each Sunday to be considered active members of the faith.

The news triggered widespread applause from members, with some posting celebratory memes on social media. It came during The Church of Jesus Christ of Latter-day Saints’ twice-yearly conference, where a leader also reaffirmed the faith’s opposition to gay marriage and its belief that gender is God-given and eternal.

“The senior leaders of the church have been aware for many years that for some of our precious members, a three-hour Sunday schedule at church can be difficult,” said Quentin L. Cook, a member of the Quorum of the Twelve Apostles, church leaders who help run the faith. “This is particularly true for parents with small children, primary children, elderly members, new converts and others.”

The three-hour commitment is a hefty one compared with some other religions’ Sunday services. Many Catholic, Lutheran and Methodist churches, for instance, offer weekly worship that lasts about an hour or an hour and a half, along with voluntary classes and other gatherings throughout the week.

Church president Russell M. Nelson called the adjustment a new “home-centered church” strategy that comes as the faith expands throughout the world. More than half of its 16 million members live outside the U.S. and Canada.

“The longstanding objective of the church is to assist all members to increase their faith in our Lord Jesus Christ and in his atonement,” Nelson said. “In this complex world today, this is not easy. The adversary is increasing his attack on faith and on families at an exponential rate. To survive spiritually, we need counter-strategies and proactive plans.”

Paulina Porras, a mother of 1-year-old twins, was ecstatic with the news. Her daughters aren’t old enough to go to children’s programs alone, so she and her husband have to care for them during Sunday church time.

“Staying three hours is impossible,” said Porras, 29, of Logan, Utah. “Two hours we can do.”

Instead of attending two meetings each Sunday beyond the one-hour worship – such as Sunday school, men’s and women’s groups – members will attend one each Sunday, with the meetings rotating throughout the month, Cook said.

Marc Fish, an insurance company owner from Las Vegas, also lauded the change. Three hours each Sunday can be intimidating for potential converts and wayward members, and the change gives families the flexibility to weave in gospel activities at home.

Fisher, 38, has seven children ranging in age from 7 to 25 who are busy with piano, volleyball and homework, he said. He plans to have more one-on-one talks with them.

“Schedules are crazy for a lot of families,” Fisher said. “Sometimes, you hear in the church we’re caught up with checklists, the pressure and the stress of just meeting everything.”

While U.S. members likely will welcome the new schedule, it seems to mainly reflect the church shifting its focus away from being heavily Western American, where most members live near chapels and can handle the three-hour Sunday commitment, or worship block, said Mormon scholar Matthew Bowman, an associate professor of history at Henderson State University in Arkadelphia, Arkansas.

“This change is geared toward making participation in the church more flexible and increasingly targeted toward smaller congregations: A shorter worship block means less volunteer demands upon the congregation, fewer jobs which need to be filled and generally easier administration,” Bowman said in an email.

Church membership growth has decreased in recent years, with membership growth in 2017 being the slowest in 80 years, according to independent Mormon researcher Matt Martinich.

The number of convert baptisms in 2017 reached the lowest level in 30 years, he said.

It’s mainly because of the slowed growth in the countries with the most members: the United States, Mexico, Brazil, the Philippines, Chile and Peru, Martinich said.

He doesn’t think the Sunday change is aimed at increasing retention, but rather at using church resources and members’ time more efficiently. The switch could allow multiple congregations to use the same church building in places like Utah where there are large numbers of members. It also will let members do personal and family gospel activities on their own time, he said.

The two-day Mormon conference kicked off a day after the faith announced it was renaming the famed Mormon Tabernacle Choir to drop the word “Mormon.” The singing group, now called the Tabernacle Choir at Temple Square, performed at the conference as they always do.

The decision to rename the choir the was the first major move since president Nelson in August called for an end to the use of shorthand names for the religion that have been used for generations by church members and the public.

Nelson didn’t mention the issue in his brief remarks, but a lower-level church leader named Paul B. Pieper called on Latter-day Saints to take up Nelson’s “prophetic call.” Pieper encouraged members to “take upon themselves the name of Jesus Christ,” which has “singular and essential power.”

The comments about gay marriage and gender came from longtime Quorum of the Twelve member Dallin H. Oaks, who called on members to oppose “social and legal pressures to retreat from traditional marriage or to make changes that confuse or alter gender or homogenize the differences between men and women.”

Oaks said those relationships and identities are “essential to accomplish God’s great plan” and that Satan “seeks to confuse gender, to distort marriage and to discourage childbearing – especially by parents who will raise children in truth.”

The comments align with past positions by the faith, which has tried to take a more welcoming stance to LGBTQ+ people while sticking with fundamental opposition to same-sex marriage and transgender operations.
