Jesus (Eisa alaihi salaam) was one of the great Prophets and Messengers (alaihim salaam). Allah sent Prophets and Messengers to guide mankind towards Tawheed which is the absolute one-ness and uniqueness of God Allah. So he could never say Father to the Almighty God and he (Jesus) could never say that he was God himself. He could never say that he was one of the three constituents of God, even he couldn't say that God is composed of three constituents.
All of these SENSELESS beliefs are false accusations on Jesus (Eisa alaihi salaam) for which the accusers shall suffer everlasting grievous punishment. That punishment shall takeover the sinners right at the time of death and then will never end.
Your question is not very clear. But I try to answer, if it is not the answer then you should make your question understandable.
Islam has been the religion of all Prophets since Adam alaihi salaam till the Final Prophet Muhammad salla Allaho alaihi wa sallam. This is the religion that Allah sent down for all human beings and for the jinns. Eisa (Jesus) alaihi salaam was from among all those Prophets alaihim salaam. Every Prophet was very great. We are not supposed to make difference among them. You can see the translation of the following verse of the Holy Quraan:
[h=2]The Messenger (Muhammad SAW) believes in what has been sent down to him from his Lord, and (so do) the believers. Each one believes in Allah, His Angels, His Books, and His Messengers. They say, "We make no distinction between one another of His Messengers" - and they say, "We hear, and we obey. (We seek) Your Forgiveness, our Lord, and to You is the return (of all)."[/h]
As you can see the underlined red part of the above mentioned verse translated into English, we as Muslims cannot make difference among the Prophets of Allah Almighty. we have to give them all great respect. So all of them, including Eisa (Jesus) alaihim salaam were the great Prophets of Islam.
Jews were basiclly Bani-Isra-eel which means the children of Isra-eel. Isra-eel was the second name of the Prophet Yaqoob (Jacob in Bible) alaihi salaam. Many Prophets were sent to them. That nation lived for very long duration extending from Yaqoob (Jacob) alaihi salaam until now and from now they will exist until the second coming down of Eisa (Jesus ) alaihi salaam from the heaven to the earth. In this long existing nation of the Bani-Isra-eel there were good knowledgeable sections for e.g. those for whom Allah sent Musa alaihi salaam to rescue them from the oppression of Pharaoh. But there were many who were extremely disobedient to the Prophets alaihim salaam. Even they killed many of them. The Holy Quraan gives in detail the blessings given to them and the disobedience that they showed. They were also punished with exemplary punishments, for e.g. a tribe was changed into apes because they didn't respect "Saturday" which was a holy day for them. They disobeyed the Command of Allah to abstain from catching fish on Saturday. So they were cursed and were changed into apes/monkeys!!!
From the above statement you will understand that the Prophets were sent to them to follow the religion Islam in total. But, of course, Tawheed has been the bases of the religion Islam at all times and by all the Prophets. Jesus also was from among those Prophets. Allah created him miraculously and showed them a unique miracle that Eisa (Jesus) alaihi salaam spoke to them when he was a new born baby in the lap of his mother. He was given Injeel (the Gospel) but it didn't have the law. So Eisa alaihi salaam had to teach them Gospel as well as Tawrah because the law was in the Tawrah.
Tawheed was the bases and that included to follow the laws and Commands of Allah. Tawheed means to believe in the absolute Oneness and Uniqueness of Almighty God, but the practical proof of the faith of Tawheed is given by acting upon the Commands and Laws of Allah. All these teachings were included in the duties of Eisa alaihi salaam. The Jews, as usual, turned against him and made a plan to kill him, but they couldn't reach him as Allah lifted him up to the heavens.
You had said that Jesus was sent to guide people towards tawheed. What I'm trying to get at is that the Jews of Jesus' time were staunch monotheists. You'd be hard pressed to find any instance of idolatry amongst them. So why was Jesus sent to them according to your understanding?
Secondly, you said he was given the Injeel. In what way was it given to him? Do you believe an angel recited to injeel to Jesus and he recited it verbatim to his followers?
Third, what did the injeel contain that was different from the Torah?
Fourth, why did the Jews according to you attempt to kill Jesus?
