When people claim that the dead have spoken, how are Christians to discern what has really taken place?
In 1856, in the midst of one of the darkest periods in Xhosa history, a young girl named Nongqawuse reported an extraordinary encounter near the Gxarha River in the Eastern Cape region of South Africa. She said that figures from the dead had appeared to her and delivered a message of coming renewal. The dead would rise, the old order would pass away, and abundance would return. But first, existing cattle had to be slaughtered and cultivation abandoned. What began with a vision eventually became bound up with a movement that contributed to catastrophic hunger, social dislocation, and the further weakening of Xhosa society. This historical event also raises a deeper theological question: when people claim that the dead have spoken, how are Christians to discern what has really taken place?
What Really Happened at the Gxarha River?
The history needs to be handled carefully. Nongqawuse shouldn’t be made the sole cause of the catastrophe. AmaXhosa were already living through colonial warfare and dispossession, political disruption, drought, crop pressures, and a devastating cattle-lung disease. A teenage girl wouldn’t have possessed the authority alone to mobilise a nation. Her uncle Mhlakaza, senior leaders, and ultimately chiefly networks helped interpret and spread the message. The spiritual world into which the prophecy arrived also mattered. Nongqawuse didn’t introduce the idea of prophetic visions into Xhosa society. Earlier figures such as Nxele and Mlanjeni had already connected visions and supernatural promises with deliverance in periods of severe social crisis.
The history needs to be handled carefully.
This complexity has produced a continuing historical debate. Historian J. J. Klaas has recently argued that the familiar Nongqawuse narrative conceals the more decisive role of European cattle lung sickness, even describing the epidemic as a biological weapon used to destroy Xhosa productive capacity. The disease was certainly devastating. But Klaas’s stronger claim goes beyond the evidence presently demonstrated. The lung-sickness epidemic began in the Cape in 1853, before Sir George Grey became governor in late 1854. More importantly, disease-control culling cannot by itself explain the prophetic commands concerning grain, the abandonment of planting, the resurrection of the dead, or the promised transformation of the social order. Treive Nicholas therefore offers a more cautious account: disease and colonial pressure were major contributing causes, while Nongqawuse’s vision was a proximate rather than solitary or primary cause. Grey could exploit the disaster without having secretly manufactured it.
There is also early Xhosa testimony that prevents us from simply dismissing the spiritual dimension as a later colonial invention. In 1888, the Xhosa intellectual W. W. Gqoba published an isiXhosa reconstruction of the movement, drawing on memories while participants were still alive. Gqoba fiercely rejected the colonial “war-plot” theory that chiefs had knowingly invented the prophecy as preparation for war. Yet Gqoba didn’t reject the reality of the prophetic movement. He described a society divided between the amathamba (those who complied with the seer) and the amagogotya (those who resisted or refused). Some genuinely believed; others complied under pressure. Lung sickness appears in this early discussion too, but it doesn’t replace the vision as an explanation. Disease, political catastrophe, social pressure, and spiritual belief existed alongside each other.
For Christians, that historical care clears the ground for a different question.
What Should We Make of the Vision Itself?
Our first response shouldn’t be to assume that every report of a supernatural experience is fabricated. Scripture doesn’t present reality as a closed material universe. It speaks of angels as “ministering spirits” (Hebrews 1:14); “spiritual forces of evil” against which believers contend (Ephesians 6:12); and of Satan as a real deceiver who even tempted Christ (Matthew 4:1-11). Human beings may therefore encounter things they cannot adequately explain by ordinary material categories. The biblical question isn’t merely: “Did you see something?” The decisive question is: “What was its source?”
An impressive experience doesn’t authenticate itself.
Scripture repeatedly commands discernment rather than credulity. “Do not believe every spirit, but test the spirits to see whether they are from God” (1 John 4:1). Deuteronomy 13 goes even further: even if a sign or wonder occurs, God’s people must reject the messenger if the message draws them away from the Lord. An impressive experience does not authenticate itself.
Acts 16 gives a striking New Testament example. A slave girl with a spirit of divination followed Paul and his companions, declaring that they were servants of the Most High God who proclaimed a way of salvation. Her words contained truth. Yet Paul didn’t conclude, “She is accurate, therefore this spirit must be from God.” He expelled the spirit in the name of Jesus Christ (Acts 16:16-18). Truthful information can come through a corrupt spiritual source. Satan himself can disguise himself as an angel of light (2 Corinthians 11:14). This brings us back to the decisive question: What was its source? An experience may be vivid, convincing, and even contain elements of truth, but none of these things establishes that it came from God. Scripture requires us to test the source.
When the Dead Appear to Speak
Testing the source is critical in African contexts, where dreams of deceased relatives are often treated as self-authenticating encounters with ancestors. A person may say, “I saw my grandmother. She spoke exactly like her. She told me things nobody else knew.” Christianity need not begin by mocking the experience. But neither may we accept the interpretation, simply because the experience was vivid. Scripture teaches that the dead don’t become roaming spiritual guides for their descendants. At the same time, deceptive spirits are real. The identity claimed in an apparition is therefore not proof of its identity.
The vision didn’t deliver what it promised. Its fruit was not resurrection but devastation.
Nongqawuse’s story gives the warning historical flesh. The message promised life. But it delivered destruction. Cattle were slaughtered. Food production was disrupted. Families and communities were divided. People waited for a renewal that never came. Whatever historical responsibility we rightly distribute among colonialism, disease, chiefs, Mhlakaza, social pressure, and believers themselves, the vision didn’t deliver what it promised. Its fruit was not resurrection but devastation.
The same pattern can appear less dramatically today. What begins as a comforting dream of a deceased relative may become a demand: accept your calling; consult a diviner; perform rituals; rearrange your life; and fear the consequences if you refuse. What first appeared familiar and reassuring becomes an authority competing with God’s word. The thief doesn’t introduce himself as a thief. Jesus says that the thief comes “only to steal and kill and destroy,” while Christ comes that his sheep may have life (John 10:10).
Christians Need Not Fear the Spirits
Christians aren’t immune from deception. Nor temptation. Jesus himself was tempted by the devil, who even quoted Scripture (Matthew 4:1-11). Yet those who belong to Christ need not fear demonic possession as though Christ and demons share ownership of the same person. Believers belong to Christ. We are in-dwelt by his Spirit. Nevertheless we must resist the devil, remain sober-minded, and test what claims spiritual authority over us.
When the supernatural appears, by what standard will we judge it?
Nongqawuse’s tragedy therefore asks a question that reaches far beyond 19th century Xhosaland. When the supernatural appears, by what standard will we judge it? Not by vividness. Nor by sincerity. Not by cultural familiarity. Not even by apparently supernatural knowledge. We test every spirit, every prophecy, every dream, and every claimed revelation by the word God has already spoken and by the gospel of Jesus Christ. The dead don’t need to speak for God. He has spoken in his Son (Hebrews 1:1-2).
