1. THE NATURE OF GOD

Christianity:

• One God in three persons (Father, Son, Holy Spirit) — the Trinity
• Matthew 28:19 — “Father… Son… Holy Spirit”
• God is relational and revealed through Christ

Islam:

• Strict absolute oneness of God (Tawhid)
• God has no partners, no division
• Rejects the Trinity completely

 Core Difference:

• Christianity: Triune God
• Islam: Absolute singular unity (no Trinity)

2. THE IDENTITY OF JESUS

Christianity:

• Jesus Christ is the Son of God, fully God and fully man
• John 1:1,14 — “The Word was God… became flesh”
• Worshiped as Lord

Islam:

• Jesus (Isa) is a prophet, not God
• Not the Son of God
• Not to be worshiped

 Core Difference:

• Christianity: Jesus is God incarnate
• Islam: Jesus is a human prophet

3. THE CRUCIFIXION

Christianity:

• Jesus was crucified, died, and rose again
• Central to salvation
• 1 Corinthians 15:3–4

Islam:

• Jesus was not crucified (commonly taught he was taken up)

 Core Difference:

• Christianity: Cross = salvation
• Islam: No crucifixion

4. SALVATION

Christianity:

• Salvation by grace through faith
• Ephesians 2:8–9 — not by works
• Based on Jesus’ finished work

Islam:

• Salvation based on faith + deeds + mercy of God
• Judgment based on works

 Core Difference:

• Christianity: Grace-centered
• Islam: Works + mercy-centered

5. SIN AND ATONEMENT

Christianity:

• Humanity is fallen; needs redemption
• Jesus is the substitutionary sacrifice
• Hebrews 9:22 — blood required for forgiveness

Islam:

• No original sin in the same sense
• Each person accountable for their own deeds
• No need for a sacrificial Savior

 Core Difference:

• Christianity: Atonement through Christ
• Islam: Personal accountability without a savior

6. SCRIPTURE

Christianity:

• Bible (Old + New Testament) is the final authority
• 2 Timothy 3:16

Islam:

• Qur’an is the final revelation
• Earlier Scriptures believed to be altered

 Core Difference:

• Christianity: Bible is complete revelation
• Islam: Qur’an is final correction

7. ASSURANCE OF SALVATION

Christianity:

• Believers can have assurance in Christ
• 1 John 5:13

Islam:

• No absolute assurance; depends on judgment

 Core Difference:

• Christianity: Assurance in Christ
• Islam: Uncertainty until judgment

8. MEDIATOR BETWEEN GOD AND MAN

Christianity:

• Jesus is the only mediator
• 1 Timothy 2:5

Islam:

• No mediator needed; direct submission to God

 Core Difference:

• Christianity: Christ as mediator
• Islam: No mediator

FINAL THOUGHT

The central dividing line is Jesus Christ.

Matthew 16:15 — “Who do you say that I am?”

Everything depends on that answer.

• If Jesus is God and Savior → Christianity stands true
• If Jesus is only a prophet → the Gospel is rejected

These are not small differences—
they are foundational and irreconcilable at the theological level.

Maranatha! Come Lord Jesus!
