In January 1994, Randy Clark, a Vineyard pastor, was invited to preach. John Arnott heard that Clark had attended a conference with Rodney Howard-Browne and had been greatly impacted by Howard-Browne's ministry. The revival started during Clark's two-month visit but continued after he left. Some religious leaders criticized the church and revival because of the teachings and manifestations that occurred. Wimber initially defended the Airport Vineyard saying "Nearly everything we've seen—falling, weeping, laughing, shaking—has been seen before, not only in our own memory, but in revivals all over the world."
