From what has been related so far, it is clear that Jesus (as) did not die but was raised to the presence of Allah. However, there is one more point that is underlined by the Qur'an: Jesus (as) will come back to earth.
The Qur'an explicitly declares the return of Jesus (as) to earth. (1)
Surah Al ‘Imran 55 is one of the verses indicating that Jesus (as) will come back:
When Allah said, "‘Isa, I will take you back and raise you up to Me and purify you of those who are disbelievers. AndI will place the people who follow you above those who are disbelievers until the Day of Rising. Then you will all return to Me, and I will judge between you regarding the things about which you differed. (Surah Al ‘Imran: 55)
The statement in the verse, "And I will place the people who follow you above those who are disbelievers until the Day of Rising" is important. Here, there is reference to a group strictly adhering to Jesus (as) and who will be kept above the disbelievers until the Day of Judgement. Well, who are these adherents, then? Are they the disciples who lived in the time of Jesus or are they the Christians of today?
During his lifetime the followers of Jesus (as) were few. After his death, the essence of the religion degenerated rapidly. Furthermore, the people known as the disciples faced serious pressure throughout their lives. During the succeeding two centuries, having no political power, those Christians having faith in Jesus (as) were also oppressed. In this case, it is not possible to say that early Christians or their successors during these periods were physically superior to the disbelievers in the world. We might logically think that this verse does not refer to them.
When we look at the Christians of today, on the other hand, we notice that the essence of Christianity has changed a lot and it is quite different from what Jesus (as) originally brought to mankind. Christians embraced the perverted belief that suggests that Jesus (as) is the son of God and similarly held the doctrine of the trinity (The Father, Son and the Holy Spirit). In this case, it is flawed to accept the Christians of today as the adherents of Jesus (as). In many verses of the Qur'an Allah states that those having faith in the trinity certainly are disbelievers:
