Davis collapsed suddenly when members of the congregation questioned him about his admitted infidelity.
But according to the local media, churchgoers were actually expressing their forgiveness when Davis unexpectedly passed away.
A church elder was quoted as saying: "We were shouting, 'We forgive you, we love you,' but the stress of all of it, he had a heart attack." Davis' official cause of death, though, has not been determined.
Police have already reviewed a video that a church member recorded while attending service. Police have also interviewed several witnesses.
Davis had been a pastor at the church he and his wife founded since 1967. He leaves behind six children and eight grandchildren.
May he rest in peace.
