Pillar III: False Religions

Islam — A Different God, A Different Christ, A Different Gospel

Why Islam Must Be Treated Seriously

Islam is not a fringe belief system. It is a comprehensive worldview with:

• Strong monotheism

• Moral seriousness

• Clear submission language

• Global influence

It claims continuity with Abraham, Moses, and Jesus — but asserts that Christianity corrupted revelation.

So we begin where we always begin:

1. Who has authority?

2. Who is God?

3. Who is Jesus?

4. How is salvation achieved?

5. Does the system remain coherent under scrutiny?

1. Authority — Final Revelation or Later Override?

The Claim

Islam teaches that:

• The Qur’an is the final, perfect, uncorrupted revelation of God

• Muhammad is the final prophet

• Previous scriptures were altered or corrupted

At first glance, this appears simple:
“God corrected previous distortions.”

But this introduces a severe historical and logical problem.

The Historical Tension

The Qur’an affirms that:

• The Torah was revelation

• The Psalms were revelation

• The Gospel was revelation

Yet the Qur’an also contradicts the central message of the Gospel — particularly regarding Christ’s divinity and crucifixion.

So which is it?

If the Gospel was genuine revelation, then it cannot teach what Islam denies.

If the Gospel was corrupted, then:

• Where is the manuscript evidence of such corruption?

• Why do all early Christian manuscripts, across regions, agree on Christ’s crucifixion and divinity?

• Why does the Qur’an not clearly identify what was changed?

The claim of corruption is asserted — not demonstrated.

Common Sense Anchor

If someone claims a book has been altered, they must show:

• What was changed

• When it was changed

• Who changed it

• Where the unaltered version is

Without that, corruption becomes a theological escape hatch.

2. Who Is God?

Islam insists on strict monotheism (Tawhid).

This is admirable in its clarity.

However, Islam rejects:

• The Trinity

• The Fatherhood of God

• The Sonship of Christ

It argues that God cannot have a Son because that would imply physical generation.

But this is a misunderstanding of Christian doctrine.

Christianity does not teach biological sonship.
It teaches eternal relational distinction within one divine being.

Islam critiques a caricature — not the actual doctrine.

The Deeper Issue: God’s Nature

In Islam, Allah is:

• Absolutely singular

• Sovereign

• Powerful

• Ultimately unknowable in essence

But here is the philosophical tension:

If God is eternally singular and not relational within Himself, then love cannot be essential to His nature — it must be conditional upon creation.

In Christianity:
God is eternally relational.
Love is not something God began doing.
It is who He is.

That distinction is massive.

3. Who Is Jesus?

This is the fault line.

Islam teaches:

• Jesus was a prophet

• Born of a virgin

• Performed miracles

• Was not crucified

• Did not rise from the dead

• Is not the Son of God

Instead, Islam claims someone else was made to appear like Jesus and crucified in His place.

This raises immediate issues.

The Historical Problem

Virtually all historical scholars — Christian, secular, and even skeptical — affirm that Jesus was crucified.

It is one of the most historically secure facts of the ancient world.

To deny the crucifixion is not merely to reject theology — it is to reject the historical consensus of antiquity.

If the crucifixion did not occur, then:

• The earliest disciples were either deceived or lying

• Thousands were willing to die for what they knew was false

• Early enemies of Christianity somehow missed correcting the story

The substitution theory is asserted in the Qur’an without historical evidence.

The Theological Collapse

If Jesus was not crucified:

• Sin was not atoned for

• Justice was not satisfied

• Grace becomes undefined

• Salvation becomes moral effort

Islam avoids the cross because it avoids the need for substitutionary atonement.

But if sin is real — and Islam affirms that it is — then justice must be addressed.

If justice is not addressed, it is ignored.

4. Salvation — Submission or Redemption?

In Islam, salvation is achieved through:

• Submission to Allah

• Obedience to the Five Pillars

• Good deeds outweighing bad deeds

• Allah’s mercy at final judgment

Notice the structure:

You submit.
You perform.
You hope.

There is no assurance.
There is no substitution.
There is no completed atonement.

Even Muhammad reportedly expressed uncertainty regarding his final standing before Allah.

The Structural Weakness

If salvation depends on:

• Performance

• Moral record

• Final mercy

Then assurance is impossible.

Grace becomes unpredictable.

In Christianity:

Justice is satisfied.
Grace is anchored.
Salvation is secured.

In Islam:

Justice is sovereign.
Mercy is discretionary.
Salvation is uncertain.

5. Judgment and Freedom

Islam strongly affirms judgment.

But without atonement, judgment becomes pure evaluation.

Freedom then becomes:

Submission to law without internal transformation.

Christianity claims something different:

Freedom is liberation from sin’s rule because judgment was borne by Christ.

Islam offers submission.
Christianity offers reconciliation.

The Central Fault Line

Islam fails at the person of Christ.

If Jesus is not:

• Eternal

• Crucified

• Risen

Then salvation becomes human effort.

And if salvation becomes effort, grace becomes fragile.

And if grace becomes fragile, freedom becomes fear.

Plain-Sense Anchor

Hold this clearly:

Any system that denies the cross must replace redemption with performance.

And performance can never secure peace.

Why Islam Persuades Many

We must be honest:

Islam offers:

• Clear moral boundaries

• Strong community

• Defined submission

• Seriousness about God

But seriousness without atonement leaves the conscience unresolved.

You can strive.
You can obey.
You can submit.

But you cannot know.
