Invesitagetruth i want to ask you what is more trustworthy the companions of the prophet(saws) and the prophet(saws) himself commenting on the verses or the so called new sects? Lets not even quote commentators, let the Quran speak for itself.
Lets read the verses...
4:156-159 "That they rejected Faith; That they uttered against Mary A grave false charge; That they said (in boast): 'We killed Christ Jesus The son of Mary, The Messenger of Allah.' But they killed him not, Nor crucified him, but so it was made to appear to them, and those who differ therein are full of doubts, with no (certain) knowledge, but only conjecture to follow, for of a surety they killed him not. Nay, Allah raised him up Unto Himself; and Allah Is Exalted in Power, Wise. And there is none of the people of the book (Jews and Christians) But must believe in him (Jesus) Before his death; And on the Day of Judgment He (Jesus) will be a witness Against them."
But they killed him not, Nor crucified him.
I am pretty sure it says not killed nor crucified so both didn't happen.
Back to the verse the false charge against Mary(p) was that she was unchaste. Such a charge is bad enough to make against any woman, but to make it against Mary(p), the mother of Jesus(p), was to bring into ridicule Allah's(swt) power itself. Islam is specially strong in guarding the reputation of women. Slanderers of women are bound to bring four witnesses in support of their accusation, and if they fail to produce four witnesses, they are be flogged with eighty stripes and debarred forever from being competent witnesses. Let us look at verse 24:4 "And those who launch A charge against chaste women, And produce not four witnesses (To support their allegations) Flog them with eighty stripes; And reject their evidence Ever after: for such men Are wicked transgressors. Unless they repent thereafter And mend (their conduct); For Allah is Oft-Forgiving Most Merciful."
Back to the verses the Basilidans believed that someone else was substituted for him. The Docetate held that Christ never had a real physical or natural body, but only an apparent or phantom body, and that his crucifixion was only apparent, not real. The Marcionite Gospel (about A.C. 138) denied that Jesus was born, and merely said that he appeared in human form. The Gospel of St. Barnabas supported the theory of substitution on the Cross.
Let us look at verse 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." Here we see that Allah(swt) promised Jesus(p) to raise him to heaven. Jesus(p) was charged by the Jews with blasphemy as claiming to be God or the son of God. The Christians (except a few early sects which were annihilated by persecution, and the modern sect of Unitarians), adopted the substance of the claim, and made it the cornerstone of their faith.
