Testing a Prophet — The Biblical Criteria
Islam asks Christians to accept Muhammad as a prophet in the biblical line. That is a fair request to examine — because the Bible itself gives tests for a prophet, and expects them to be used.
Test 1 — Predictive accuracy
Deuteronomy 18:21–22
"If what a prophet proclaims in the name of the LORD does not take place or come true, that is a message the LORD has not spoken." A single failed prediction is disqualifying. This sets a high bar, and it is meant to.
Test 2 — Theological fidelity
Deuteronomy 13:1–3
Even a prophet who performs a sign is to be rejected if he calls people to "other gods" — that is, away from the God already revealed. Signs alone are never enough; the message must be consistent with prior revelation.
Test 3 — Continuity with what came before
The New Testament writers add that any later message is measured against the apostolic gospel (Galatians 1:8 — "even if we or an angel from heaven should preach a gospel contrary to the one we preached, let him be accursed") and that the Spirit of prophecy testifies to Jesus (Revelation 19:10; 1 John 4:2–3). A prophet who denies the crucifixion, the resurrection, and the deity of Christ is not extending the biblical line but breaking with it.
Applying the tests
The Qur'an affirms Jesus's virgin birth, miracles, and messiahship — but denies that he was crucified (Surah 4:157), denies that he is the Son of God, and gives a different account of salvation. On the biblical criteria, that is the decisive point: the disagreement is not about details but about the identity of Christ and the meaning of the cross, which the New Testament treats as the heart of the gospel. The claim that Muhammad is the "prophet like Moses" of Deuteronomy 18:18 is examined on its own terms in the Deuteronomy 18 section — where the earliest Christians (Acts 3:22; 7:37) identify that prophet as Jesus.
💡 Testing a Prophet — Reasonable Summary"The Bible gives its own tests for a prophet and expects them used. Predictive accuracy: a single failed prediction disqualifies (Deuteronomy 18:21–22). Theological fidelity: a prophet who calls people away from the God already revealed is rejected even if he works signs (Deuteronomy 13:1–3). Continuity: the New Testament measures any later message against the apostolic gospel (Galatians 1:8) and says the Spirit of prophecy testifies to Jesus (Revelation 19:10). Applied to Islam, the decisive issue is not details but the identity of Christ and the meaning of the cross — the Qur'an denies the crucifixion (Surah 4:157) and the divine Sonship, which is a break with the biblical line, not an extension of it. And the 'prophet like Moses' of Deuteronomy 18:18 is identified by the earliest Christians (Acts 3:22; 7:37) as Jesus."
