KDKA and the First Radio Worship (1921)

On January 2, 1921, worship from Calvary Episcopal Church in Pittsburgh, Pennsylvania, was broadcast live on KDKA, America’s first licensed radio station. Barely two months after KDKA began regular transmissions, the station carried Scripture, prayer, and preaching into homes through crystal sets and headphones. Many listeners had never before heard a church service beyond their own walls; now the sanctuary’s words crossed neighborhoods and distances on unseen waves.

Pittsburgh in the early 1920s was an industrial city marked by labor, soot, and rapid change. The nation was still recovering from the Great War and the influenza pandemic, and countless families knew grief, weakness, and isolation. In that setting, a broadcast service was more than a technical curiosity—it was a pastoral answer for the sick, the elderly, the grieving, and the homebound. The airwaves became a kind of roadway for consolation and truth.

Calvary Episcopal Church, Pittsburgh

Calvary Episcopal Church’s willingness to open its worship to microphones reflected a steady confidence that the gospel is not hindered by walls. The congregation treated radio as a trust to be used wisely, not a stage for performance. The gathered church still mattered, yet this outreach extended mercy to those unable to attend, reminding them they were not forgotten.

This was a quiet form of heroism: ordinary believers embracing an unfamiliar tool for the sake of love. It required courage to be early, visible, and potentially criticized, and it required humility to keep the message central rather than the medium. Their action anticipated later ministries that would carry biblical preaching to prisons, hospitals, and distant towns—places where a visitor might be delayed, but God’s Word could arrive.

Stewardship of the Airwaves

The broadcast embodied the conviction that Christ’s message is for every household. “How can they believe in the One of whom they have not heard? And how can they hear without someone to preach?” (Romans 10:14). It also echoed the promise, “So shall My word be that goes forth from My mouth: It will not return to Me void” (Isaiah 55:11).

By consecrating a new invention to an ancient faith, Calvary’s leaders and worshipers modeled compassion, evangelistic zeal, and trust that God can use even crackling signals to awaken hearts and strengthen weary saints.
