If there are problems in the pews these days, most pastors will learn about them the way they learn about almost everything else -- their smartphones will blow up.

It may be a text messages, a blitz of tweets or an online post that ignites a long comments thread with the faithful trading theological jabs or making pious, passive-aggressive remarks about church life. Other messages will be specific and personal, often leaving pastors confused about the urgency of these terse signals.

"People can create online personalities that are simply not real. … A lot of what they say in social media has little to do with who they really are and all the fleshy, real stuff that's in their lives," said the Rev. John Jay Alvaro, of First Baptist Church in Pasadena, Calif.

Thus, Alvaro and the church's other clergy are committed to this strategy: Always move "one step closer" to human contact. "What we want is coffee cups and face-to-face meetings across a table. … You have to get past all the texts and emails and Facebook," he said.

In fact, Alvaro is convinced that online life has become so toxic that it's time for pastors to detox. Thus, he recently wrote an essay for Baptist News Global with this blunt headline: "Pastors and other church leaders: Give up social media. Not for Lent, but forever." His thesis is that the "dumpster fire" of social-media life is making it harder for pastors to love real people.

To quote one of Alvaro's Duke Divinity School mentors -- theologian Stanley Hauerwas -- today's plugged-in pastor has become "a quivering mass of availability."

"Any benefit you perceive social media is giving you pales when compared to the real losses of cultivating your online social presence," wrote Alvaro. "Or take it from the other direction. If everyone in your congregation got off Facebook, Twitter, Instagram, Snapchat, etc., your ministry and your pastoral life would improve immediately. Well, not immediately. First there would be withdrawal, anger and other addictive reactions. Drugs don't leave your system peacefully."

After evaluating his own experiences in ministry, and talks with other pastors, Alvaro thinks that many people don't understand that social media programs are designed to amplify messages -- especially "negative emotional content" -- so that they spread as far as possible, as fast as possible.

This commercial system is "built to make you angry or sad, but with the promise that good news is one more scroll away. It is a slot machine of empty promises," he wrote.
