LifeWay Makes Cuts After VBS, Sunday School Sales Drop

The Southern Baptist publisher plans to restrict its budget by at least $25 million through reducing staff and salaries.

LifeWay Christian Resources, the publishing entity of the Southern Baptist Convention, has announced it will cut roughly 10 percent of its operating budget through staff reductions, a hiring freeze, and salary cuts.

The move comes after five consecutive weeks of steep revenue decline in the wake of the coronavirus and the expectation that sales may not rebound anytime soon.

The Nashville-based Christian publisher said revenue is down 24 percent compared with the same period last year, largely due to a sharp drop in bulk orders from churches for resources such as Sunday school curricula, Bible study materials, and Vacation Bible School curricula.

It’s not clear yet if SBC churches or other churches that buy LifeWay materials will hold VBS or camp programming this year.

LifeWay’s budget for this fiscal year is $281.3 million. It said it planned to cut between $25 million and $30 million from its budget.

The announcement is just the first indication of the financial blow many US churches and denominational agencies are facing as a result of the COVID-19 shutdowns—a blow that could reshape the religious landscape for decades to come.

“LifeWay stands to lose tens of millions of dollars of revenue that the organization would normally generate over the summer months from camps, events, VBS, and ongoing curriculum sales,” said Ben Mandrell, LifeWay’s CEO, in a news release. “LifeWay is mitigating these losses as much as possible through various expense reduction plans, including staff reductions and cuts in non-employee expenses.”

LifeWay said members of its executive leadership team will give up one month’s salary beginning in May. It did not say how it would achieve a staff reduction, ...

Grad schools dropping the GRE requirement and AIs play capture the flag

Up until this year, most U.S. graduate programs in the sciences required the General Record Examination from applicants. But concerns about what the test scores actually say about potential students and the worry that the cost is a barrier to many have led to a rapid and dramatic reduction in the number of programs requiring the test. Science Staff Writer Katie Langin joins host Sarah Crespi to talk about this trend and how it differs across disciplines. Also this week, Sarah talks with DeepMind’s Max Jaderberg in London about training artificial agents to play a video game version of capture the flag. The agents played approximately 4 years’ worth of Quake III Arena and came out better than even expert human players at both cooperating and collaborating, even when their computer-quick reflexes were hampered. And in this month’s book segment, new host Kiki Sanford interviews Marcus Du Satoy about his book The Creativity Code: Art and Innovation in the Age of AI. This week’s episode was edited by Podigy.
