It is not an issue for the Muslims!
To say that the Qur’an does not address the doctrine of the incarnation is incorrect.
Trinitarian belief in the incarnation is affirmed by these words:
'I believe in one God, the Father almighty, maker of heaven and earth and of all things visible and invisible. And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all ages, God of God, Light of Light, very God of very God, begotten not made…….' (from the Nicene Creed).
This is saying there is only one God. "Lord" is someone who has authority over another -- the Messiah.
JESUS: You call me Teacher and Lord - and you are right, for that is what I am. (John 13:13)
Allāh (subḥānahu ūta'āla) issues the following denial:
'Say: ''He is Allāh the One, Allāh the eternal. He begot no one nor was He begotten. No one is comparable to Him.''' (Al-Ikhlas: 1-4).
The word ‘beget’ means to father another being that is of the same nature and qualities as oneself. The only being that Allāh (subḥānahu ūta'āla) could possibly beget* is another being like Himself; certainly not a man. But the Exalted does not beget!
Psalm 2:7
I will tell of the decree; The Lord said to me, "You are My son; this day have I begotten you.
The Qur'an says that God does not beget like humans do. The commentary in my Qur'an interpretes what the Qur'an says correctly.
"It is a derogation from the glory of God in fact it is blasphemy to say that God begets sons, like a man or an animal. The Christian doctrine is here emphatically repudiated.
If words have any meaning, it would mean an attribution to God of a material nature, and of the lower animal functions of sex."
You of all people should know this is not what Christians believe.
* Setting aside the question: ‘Is it logically possible for Allāh (subḥānahu ūta'āla) to create another like Himself?’
He didn't.
Allāh (subḥānahu ūta'āla) tells us that: ‘There is nothing like Him (ka’mith'lihi).’ (Al-Shura 11).
Ka’mithlihi is a word that uses two letters to describe likeness. The first (‘kaf’) is used to liken one thing to another to a great degree. The second (‘mithl’) likens one thing to another to a small degree. Linguistically, therefore, Allāh (subḥānahu ūta'āla) is telling us that nothing at all can be compared to Him, not in the slightest degree. This amounts to a denial of Yeshua (radi Allahu 'anhu)’s supposed ‘divine nature’.
The Bible says the same thing.
To whom then will you liken God? Or what likeness will you compare with Him? Isaiah 40:18
Darrel Pack writes:
'It is a deadly, demonic deception that Islam presents a story about Jesus, yet strips him of the title Savior. The Quran has much to say about the nature of (the Messiah). The core message in this regard is that he is neither God nor the Son of God. He is a man of great spiritual significance, but only a man. Quranic descriptions of (the Messiah) included some very elevated titles but these titles are all interpreted downward and become little more than honorifics.' ('The Quranic Jesus: A Demonic Deception: An Evangelical Assessment of Jesus in the Quran; Book 1').
I fail to see why you posted this since it is a book against the Qur'an, as Amazon says:
"This concise and direct book is a precise description of what the Quran (Qur'an, or Koran) says about Jesus Christ. It shows how Muhammad, the prophet of Islam, distorts the key teachings of the Bible about the life, teachings, death, and nature of Jesus Christ. Today we find Muslims claiming that they love and follow Jesus Christ, but is the Jesus they present the Jesus of the Bible or a Jesus that contrasts and conflicts with the Biblical Jesus Christ.
The Quran presents to us a demonically distorted version of Christ and this book looks at the key Quranic texts and the Arabic originals of those texts to discover what the Islamic holy book says about Jesus. Muhammad bin Abdullah, the illiterate prophet of Islam, lived 600 years and 600 miles from where Jesus lived and taught. From mystical experiences he received messages about Jesus Christ. These messages present a radical anti-biblical picture of who Jesus was and what he did. The Quran does not have one single New Testament quote from Jesus Christ. The Quranic Jesus is a mere prophet, he is not the Son of God, God the Son, humanity's teacher and guide, or the Savior. He was a prophet, nothing more, and his main prophetic task was simply to tell people that Muhammad was coming. In the Quran, Jesus becomes a forerunner, John the Baptist-like figure for Muhammad.
This demonic distortion is entrenched in the Muslim psyche and through writers like Ahmad Deedat, Shabbir Ally, Jamal Badawi and many others, it is making inroads in the West today."
Jesus said:
After Jesus said this, he looked toward heaven and prayed:
“Father, the hour has come. Glorify your Son, that your Son may glorify you. 2 For you granted him authority over all people that he might give eternal life to all those you have given him. 3 Now this is eternal life: that they know you, the only true God,
and Jesus Christ, whom you have sent. 4 I have brought you glory on earth by finishing the work you gave me to do. 5 And now, Father, glorify me in your presence with the glory I had with you before the world began.
Sorry, but it appears you don't know either one.
