The pastor of University Baptist Church was performing a baptism Sunday and standing in water up to his shoulders.
There are conflicting reports as to what happened next.
Some say a microphone fell into the baptismal waters.
Others say Pastor Kyle Lake grabbed the microphone while in the water.
Either way, Lake was electrocuted in front of the congregation.
Lake was taken by ambulance to a Waco hospital, where he was pronounced dead.
The woman being baptized, whose name was not released, was not injured.
Lake was at University Baptist for nine years, the past four as senior pastor.
He is survived by a wife and three children.
