Although he was an ordained minister with the evangelical Reformed Church of America, he got his start to prominence in a most unorthodox way. He started his church literally as a drive-in church:
Schuller's evangelical Protestant ministry, part of the Reformed Church in America, was a product of modern technology. He and his late wife, Arvella, an organist, started a ministry in 1955 with $500 when he began preaching from the roof of a concession stand at a drive-in movie theater southeast of Los Angeles.
