The differences are on whether Jesus was a God who wanted to be Worshipped or The Messiah & Prophet who worshipped God:

Listen to God in the Bible and Quran reminding us that he is ONE GOD Not a Trinity of three divine deities; Son, Father or Holy Ghost. Even Jesus himself didnt believe in the Trinity of (3 in 1) Gods; Judge for yourself:

Jesus Said: "The Lord our God, the Lord is One. Love the Lord your God with all your heart and with all your soul, with all your mind and with all your strength... You are right in saying that God is One, and there is no other but Him". (Mark 12:29, 30, 32)

"Why do you call me good?" Jesus answered. "No-one is good- except God alone. Luke 18:18

Your God is One God. There is no god but Him..(Quran,2:163)

Jesus:"These people honour me with their lips, but their hearts are far from me, And IN VEIN DO THEY WORSHIP ME, teaching doctrines and commandments OF MEN:"Bible-Matthew 15:7

Jesus Said: "Many will say to me on that day (Day of resurrection), Lord Lord did we not prophesy in your name and in your name drive out demons and perform many miracles? And then I will declare to them, 'I never knew you; DEPART FROM ME, YOU WHO PRACTICE LAWLESSNESS". Bible-Matthew 7:22

But if you turn away and forsake the decrees and commands I have given you, and go off to serve other deities and worship them, then I will uproot Israel from my land. Bible-2 Chronicles 7:19-20

A common misconception: Allah is an Arabic-Semetic translation of the Name of The One-God (Jehovah/Elohim/Yehweh) of the Bible-Old Testament. Muslims Worship the same One-God that Jesus, Moses and Abraham used to Worship and taught about. The One-God was given names to differentiate him from other Pagan-Gods: Zeus, Buddha, or Mithras"Son of God":

Abraham: worshipped The One-God"El Shaddai"
Moses: worshipped ..The One-God "Yahweh"
Jesus: worshipped ..The One-God "Elah"
Muhammad: worshipped .The One-God "Allah"

'And behold! (God)Allah will say (on the Day of resurrection ): " O Jesus, son of Mary! Did you say unto men: 'Worship me and my Mother as two gods besides Allah?'" He will say: " Glory be to you! It was not for me to say what I had no right (to say). Had I said such a thing, you would surely have known it. You know what is in my inner-self though I do not know what is in Yours, truly, You, only You, are the All-knower of all that is hidden and unseen."Never did I say to them aught except what You (God-Allah) did Command me to say: "Worship Allah, my Lord and your Lord.' And I was a witness over them while I dwelt amongst them, but when You took me up, you were the Watcher over them, and You are a witness to all things.' Quran 5:116

Jesus Said:"Whoever then goes against the smallest of these laws, teaching men to do the same, will be named least in the kingdom of heaven; but he who keeps the laws, teaching others to keep them, will be named great in the kingdom of heaven". Matt 5:19

Paul : Know that a man is not justified by observing the law(Commandments).. because by observing the law no-one will be justified. Galatians 2:16

Paul:All who rely on observing the law(Commandments) are under a curse.Galatians3:10

Jesus said:"If you keep my laws, you will be ever in my love, even as I have kept my Father's laws, and am ever in his love. John 15:10

"Such men are false apostles, deceitful workmen, masquerading as apostles of Christ.
And no wonder for Satan himself masquerades as an angel of light." Bible-2Corinthians11:13

Jesus Warned:"They exchanged the truth of God for a lie, and worshiped and served created things rather than the Creator-Who is forever praised".Bible-Romans 1:25

If a prophet, or one who foretells by dreams, appears among you and announces to you a miraculous sign or wonder, and if the sign or wonder of which he has spoken takes place, and he says, "Let us follow other gods" (gods you have not known) "and let us worship them, you must not listen to the words of that prophet or dreamer. The LORD your God is testing you to find out whether you love him with all your heart and with all your soul. It is the LORD your God you must follow, and him you must revere. Keep his commands and obey him; serve him and hold fast to him. Bible-Deuteronomy13:3

Question: If a False prophet came to Moses & announced that Jesus was God (God as Jesus was a different belief & unknown to Moses) Moses would have certainly advised his people as the above verse warned; not to follow or listen this false Prophet?!

Bible distorted to Make Jesus God:
How can you say, "we are wise for we have the law of the Lord." When actually the lying pen of the scribes has handled it falsely ? Bible-Jeremiah 8:8

Therefore woe be unto those who write the Scripture with their hands and then say, "This is from Allah (God)," that they may purchase a small gain therewith. Woe unto them for that their hands have written, and woe unto them for that they earn thereby. Quran 2:79
