Adult Education Series: The End of the (Main) Line?

The Surprising Past & Uncertain Future of an American Protestant Powerhouse

October 23 – November 20, 2022

9:30 a.m. | Assembly Room

As Presbyterians, we are part of a much wider stream within American Protestant life, often called the Mainline. This tradition was long a powerhouse, which wielded vast influence across all sectors of society. But in recent years most of the headlines it has garnered have centered on its decline. In this series we will revisit the Mainline’s surprising past, paying especially close attention to how this unwieldy Protestant coalition navigated the fierce challenges of the 20th-century public square. Along the way we will also wrestle with the uncertainties of the Mainline’s present and future. In this moment of flux and crisis, where might God be leading us?
