Answers:
There are I believe, several possibilities to consider and they all make perfect sense. However, the idea that God has a son, is not one that makes sense. First, let me explain why I would not accept the concept of the real God of Abraham and Moses having a son.
1. The Quran (which has never been altered or changed) says so - in the original language:
"Lam yalid wa lam yulad, wa lam yakul lahu kufwan ahad" (He (Almighty God) is not the father of anyone, nor is He the offspring of anyone; He is Uniquely One).
"Lam yalid wa lam yulad, wa lam yakul lahu kufwan ahad" (He (Almighty God) is not the father of anyone, nor is He the offspring of anyone; He is Uniquely One).
2. The Bible (which has been altered and does not exist in the original text of Hebrew any longer) says so. Look in Numbers 23:19
"God is not a man - that He should sin and He is not the son of man, that He should repent."
Let us look now to the verses you refer to in the English translation of the Greek translation of the Hebrew manuscripts called the Bible.
You said in your letter to us:
In the book of Isaiah, chapter 9 verses 6 and 7.
Isaiah, 9: 6-76 For to us a child is born,
to us a son is given,
and the government will be on his shoulders.
And he will be called
Wonderful Counselor, Mighty God,
Everlasting Father, Prince of Peace.7 Of the increase of his government and peace
there will be no end.
He will reign on David's throne
and over his kingdom,
establishing and upholding it
with justice and righteousness
from that time on and forever.
The zeal of the LORD Almighty
will accomplish this.
You asked:
Who is the son who is called Mighty God? Coming from a Christian perspective it's obviously about Jesus, but you and I know that Jesus and God are not the same entity. So who or what could be described here?
I have nine (9) items to offer for your consideration on these three (3) verses in Isaiah:
First, we don't know what the original actually said, because it has not existed for over 1600 years at least (see our references to the Council of Nicea and the Catholic Church's admissions on: www.bibleIslam.com)
Second, even the text itself does not say who the one is being talked about (could be David, peace be upon him) - take a look at Psalms 2:7 when The Psalmist says that God decreed David to be the "begotton son of God".
Third the statement says he would be "called" those things - but it doesn't say "He is" those things. Notice, there are commas between the attributes being mentioned here. This means clearly, it is a list of names that are seperate and not joined together. This is similar to someone saying, "She is a good teacher, a mighty mean lady, housekeeper and a pretty good bowler too."
Fourth, according to the Biblical references being offered as the New Testament, Jesus denounced people who would come to him on the Day of Judgment calling him "Lord, Lord" and he will say to them, "I never knew you" (The New Testament is highly doubtful actually, see our website and my bookonline <free> at: www.911Bible.com and read "Bible: A Closer Look").
Fifth, it could be talking about what really did happen to Jesus, peace be upon him. We know as Muslims from the Quran and the sayings of Muhammad, peace be upon him, that Jesus was called "son of God" (may Allah save us from such statements, ameen) by people claiming to be followers of Jesus at the time of Muhammad, peace be upon him. And certainly, without doubt many people today do say that Jesus, peace be upon him, is the son of God (may Allah save us from such statements, ameen). But you notice, if you read carefully, the Bible never says that Jesus, peace be upon, ever came out and said this himself. I was actually others saying it about him.
Sixth, the reference to the counselor more describes Muhammad, peace be upon him, than it does Jesus, peace be upon him, because Jesus did predict the one to come after him as being "Ahmad" (Quran 61:6) and the New Testament still has some things about this "counselor" mentioned in the Gospel of St. John, chapters 14 and 16.
Seventh, calling Jesus, peace be upon him, the "father" is real strange. After all, we don't see any evidence that Jesus, peace be upon him, ever got married or had a family and he nor anyone at his time ever called him "father". Strange too, the Catholics call their priests "father" but they don't call the bishops or cardnals "father" and they don't refer to the Jesus, peace be upon him, as the father - they call him the son (may Allah forgive me and keep us away from this blasphemy, ameen).
Eighth, the title "Prince of Peace" for Jesus, peace be upon him, is also something not in line with the New Testament as it exists today, but it is in line with the teachings of Islam. According to the New Testament authors, Jesus, peace be upon him, negates this concept entirely with the words, "Do not think I came with peace. I did not come with peace, but rather a sword..." He is also attributed with words about "sell your cloak and buy a sword" and "whoever lives by the sword, dies by the sword."
Interestingly enough, the word "sword" (and there are more than a dozen words in Arabic for sword) does NOT appear even once- anywhere in the Quran.
Ninth, according to the prophet Muhammad, peace be upon him, when Jesus, peace be upon him, returns to earth in the Last Days, the false Christ (Messiah Dajjal) will be destroyed by him and those who believe in Jesus, peace be upon him, will then live in peace on earth for the remainder of their lives, before dying and going to paradise.
This all seems to me, to fit rather well with the over statements in the last part of what you quoted. (this is cut very short in consideration of the limited space for an email).
I will leave the final conclusion to your own mind. If you want some real good guidance on this matter, I might suggest what I did over 17 years ago - this week - ask God. Just turn your heart over to Him completely and ask Him to open up your mind and heart to the actual truth - and if you are sincere, then there is no doubt in my mind you will find the answers that Almighty Allah wants you to find.
Thanks for a great letter and for taking the time to read this long reply.
May Allah's Guidance, and Peace and Salvation be with you - forever, ameen.
