Shirk: The Unpardonable Sin of Islam is To Believe That Jesus Christ Is God

CJK notes:

Mohammedanism has defined itself as the purest manifestation of the spirit of Antichrist. God speaking through John lays it out in First John chapter 4. 

Of course other religions deny the deity of Christ Jesus, but Mohammedanism makes it a central point. 

Look up Shirk, the unpardonable sin of Mohammedanism. Read First John and see that they are diametrically opposed. 

Indeed, the worst sin one can commit in Mohammedanism is to confess that Jesus is the Son of God. 

Makes ya wonder who would build that into their religion.

From Just Ask Islam:

Is it Shirk (making partners with Allah) to call another person Allah or something Allah, or to call a false god? How can the Christians be forgiven if they call Jesus Christ God? Is this unforgivable? 

To get salvation, you draw close to Allah and it's Allah by His Rahmah (His grace) that you are saved. You are not saved except by the grace, nobody is saved except by grace. It's by Allah’s grace, His mercy that we are saved by, and He extends that to those who worship Him alone without partners. They do not break those two commandments that I just quoted to you, because those are the same commandments in the New Testament. I read to you already from Surah an-Nisa, chapter 4, verse 48. Allah says He does not forgive (La Yaghfiru), He does not forgive the setting up of partners with Him in worship, but anything less than this, He can forgive it. And who ever has committed this Shirk or association with Him, his “partners,” then they have invented a monstrous thing and they will not be forgiven for that. 

Sheikh Yusuf Estes

I will add that not only is Jesus Christ the Son of the Living God, begotten of the Father [the only-begotten; that is, of the essence of the Father, God of God,] Light of Light, very God of very God, begotten, not made ...

and not only does that mean that God the Father has a partner in Creation ...

but,

God, through his Son Jesus, has made partners of mere human beings:

Jesus Prays for All Believers 

“My prayer is not for them alone. I pray also for those who will believe in me through their message, that all of them may be one, Father, just as you are in me and I am in you. May they also be in us so that the world may believe that you have sent me. I have given them the glory that you gave me, that they may be one as we are one— I in them and you in me—so that they may be brought to complete unity. 

Then the world will know that you sent me and have loved them even as you have loved me.

 And what does Islam teach about Jesus?

Jesus they believe was a prophet not God.

And, according to Islam, Jesus did not die on the cross but instead they believe He tricked His disciples into thinking He died on the cross,when in actuality Judas - they say - died in Jesus’ place.

In the last days they claim Jesus will die and rise and come back with their Al-Mahdi and will kill all the Jews.
