The term true Christian according to the Quran :
refers to those who follow the religion of Jesus, not a religion about Jesus
what is the religion of Jesus?
42:13
The same religion has He established for you as that which He enjoined on Noah - the which We have sent by inspiration to thee - and that which We enjoined on Abraham, Moses, and Jesus: Namely, that ye should remain steadfast in religion, and make no divisions therein: to those who worship other things than Allah, hard is the (way) to which thou callest them. Allah chooses to Himself those whom He pleases, and guides to Himself those who turn (to Him).
but was the message of Jesus identical to that by Moses?
The gospel was not only a book of wisdom and preaching:
5:46 And in their footsteps We sent Jesus the son of Mary, confirming the Law that had come before him: We sent him the Gospel: therein was guidance and light, and confirmation of the Law that had come before him: a guidance and an admonition to those who fear Allah.
43:63 When Jesus came with Clear Signs, he said: "Now have I come to you with Wisdom, and in order to make clear to you some of the (points) on which ye dispute: therefore fear Allah and obey me.
But also a book of some new easy laws:
3:50 "'(I have come to you), to attest the Law which was before me. And to make lawful to you part of what was (Before) forbidden to you; I have come to you with a Sign from your Lord. So fear Allah, and obey me.
The true followers of the message of Jesus stay on Earth till day of judgment
3:52 When Jesus found Unbelief on their part He said: "Who will be My helpers to (the work of) Allah." Said the disciples: "We are Allah's helpers: We believe in Allah, and do thou bear witness that we are Muslims.
3:55 Behold! Allah said: "O Jesus! I will take thee and raise thee to Myself and clear thee (of the falsehoods) of those who blaspheme; I will make those who follow thee superior to those who reject faith, to the Day of Resurrection: Then shall ye all return unto me, and I will judge between you of the matters wherein ye dispute.
2:136 Say ye: "We believe in Allah, and the revelation given to us, and to Abraham, Isma'il, Isaac, Jacob, and the Tribes, and that given to Moses and Jesus, and that given to (all) prophets from their Lord: We make no difference between one and another of them: And we bow to Allah (in Islam)."
57:27 Then, in their wake, We followed them up with (others of) Our apostles: We sent after them Jesus the son of Mary, and bestowed on him the Gospel; and We ordained in the hearts of those who followed him Compassion and Mercy. But the Monasticism which they invented for themselves, We did not prescribe for them: (We commanded) only the seeking for the Good Pleasure of Allah. but that they did not foster as they should have done. Yet We bestowed, on those among them who believed, their (due) reward, but many of them are rebellious transgressors.
61:14 O ye who believe! Be ye helpers of Allah. As said Jesus the son of Mary to the Disciples, "Who will be my helpers to (the work of) Allah." Said the disciples, "We are Allah's helpers!" then a portion of the Children of Israel believed, and a portion disbelieved. But We gave power to those who believed, against their enemies, and they became the ones that prevailed.
In light of the Quranic verses we can define the term true Christian ,in accordance to 3 stages:
1-The life time of Jesus
any follower of the teachings ,new laws(of the gospel) been preached by Jesus.
2- After the life time of Jesus
any follower of the laws of the Torah , apply them, reject both the trinity and the concept of Jesus atoned sins...
under this category included lots of Jews,Ebionites and other groups whose work been discovered as the Gospel of Thomas ,and those whose work still under the sand yet to be discovered.
3- The coming of Islam
Once Islam comes , his set of laws which been documented ,been affirmed as the last message God sent,has to be followed.......
