How Islam views Judaism and Christianity?

In the Name of Allah, the Most Gracious, the Most Merciful

 How Islam views Judaism and Christianity?

 Islam calls Jews and Christians as 'the People of the Book' to whom came the great Prophets including Moses (Musa) and Jesus (Isa). Islam invites them to cooperate in what is common between them and Islam. In the respective Prophets' time they were also called Muslims as God Almighty said in the Holy Qur'an about Prophet Abraham, the forefather of Moses and Jesus, peace be upon them, in the following words:

Say: "O people of the Book! Let us get together on what is common between us and you: that we shall worship none but Allah (the One and only True God); that we shall not associate any partners with Him; that we shall not take from among ourselves any lords beside Allah." If they reject your invitation then tell them: “Bear witness that we are Muslims (who have surrendered to Allah).” O people of the Book! Why do you argue with us about Abraham as to whether he was a Jew or a Christian? You know that the Torah and the Gospel were revealed long after him? Have sense at all? So far, you have been arguing about things of which you had some knowledge! Must you now argue about that of which you know nothing at all? Allah knows while you do not. Abraham was neither a Jew nor a Christian but he was a Muslim, true in faith. He was not one of the Mushrikeen (who set up partners with Allah). Al-Qur'an 3: 64-67

Muslims are required to believe in all the Holy Scriptures revealed to various Prophets in the following words:

Say: "We believe in Allah and that which is revealed to us; and what was revealed to Abraham, Ishmael, Isaac, Jacob and their descendants, and that which was given to Moses, Jesus and other Prophets from their Lord. We make no distinction between any of them, and to Him (Allah) we have surrendered ourselves (in Islam). So, if they believe (accept Islam) like you have believed, they shall be rightly guided; if they reject it, they will surely fall into dissension (divide into differing factions); Allah will be your sufficient defender against them, and He hears and knows everything.
Baptism is the baptism of Allah; and who is better than Allah in baptizing? Him do we worship. Say (O Muhammad): “Would you dispute with us concerning Allah, who is our Lord and your Lord as well? We shall be accountable to Him for our deeds and you for yours; to Him Alone we are devoted. Do you claim that Abraham, Ishmael, Isaac, Jacob and their descendants were all Jews or Christians? Say: Are you more knowledgeable than Allah?” Who is more unjust than the one who hides the testimony received from Allah? Allah is not unaware of what you do. Al-Qur'an 2:136-140

Muslims are allowed to eat the food and marry chaste women from the People of the Book. What can be more intimate relationship than husband and wife - basic unit of future generations. God says in the Holy Qur'an:

Today all good clean things have been made lawful for you; and the food of the People of the Book (Jews and Christians) is also made lawful for you and your food is made lawful for them. Likewise, marriage with chaste free believing women and also chaste women among the People who were given the Book before you is made lawful for you, provided that you give them their dowries and desire chastity, neither committing fornication nor taking them as mistresses. Anyone who commits Kufr with Imân (rejects faith), all his good deeds will become void (zero) and in the hereafter, he will be among the losers. Al-Qur'an 5:5
