Dear sister ,
you have just provided one of the problems which make such gnostic based stories to be rejected entirely ,was Jesus betrayed by a disciple or had asked a disciple for a favor in return of a heavenly reward ! ?
in other words
a man betrayed jesus or a man helped him!!?
such narrations would not only make some wonder why would Allah if wanted to save jesus put someone else in his place ? what was the rationale for doing this?,but also it seems offenesive to one of the disciples (may Allah bless their souls) accusing him of being a traitor !!!
Such blessed disciples who been praised all without exception in the holy Quran:
[005:111] "And behold! I inspired the disciples to have faith in Me and Mine Apostle: they said, 'We have faith, and do thou bear witness that we bow to God as Muslims'".
[003:052] When Jesus found Unbelief on their part He said: "Who will be My helpers to (the work of) God?" Said the disciples: "We are God's helpers: We believe in God, and do thou bear witness that we are Muslims.
[061:014] O ye who believe! Be ye helpers of God: As said Jesus the son of Mary to the Disciples, "Who will be my helpers to (the work of) God?" Said the disciples, "We are God's helpers!"
As I have learned from reflecting the Glorious Quran,and have stated in one thread before.....
narrations could either elaborate the verse,or build a wall between the reader and the verse...
It is high time for the Quran reflectors to skip such Gnostic wall and go directly to the verse which is very clear ....... any information been circulated after the departure of Jesus was mere a conjecture ,which been in every kind and color......
one last question:
would the believe in such conjecture (whether, been killed,substituted,travelled and married etcc )harm the message of jesus or the faith of his followers?
in other words
suppose someone been taught the gospel and the law ,and once he listened to conjecture that Jesus been killed,would he no longer considered to be a believer ?
the answer is absolutely not...
