Here is some background and Biblical Scholars on this issue...
Scholars who agree
This understanding is far from unique. Many Biblical scholars have challenged the so-called orthodox view that Christ somehow took Adam’s pre-Fall nature rather than the human equipment inherited by every other child of Adam. Among them are Edward Irving, Thomas Erskine, Herman Kohlbrugge, Eduard Bohl, Karl Barth, T. F. Torrance, Nels Ferre, C. E. B. Cranfield, Harold Roberts, Lesslie Newbigin, E. Stauffer, Anders Nygren, C. K. Barrett, and Eric Baker.

Wolfhart Pannenberg wrote (1964): “The conception that at the Incarnation God did not assume human nature in its corrupt sinful state but only joined Himself with a humanity absolutely purified from all sin contradicts not only the anthropological radicality of sin, but also the testimony of the New Testament and of early Christian theology that the Son of God assumed sinful flesh and in sinful flesh itself overcame sin.”
18
None of these men believed that Christ sinned in either thought or act or that because He took fallen sinful flesh He needed a Saviour. Generally speaking, the term
sinful flesh means the human condition in all of its aspects as affected by the fall of Adam and Eve. Such a nature is susceptible to temptation from within as from without. Contrary to the Grecian dualism that early pervaded much of orthodox Christianity, the flesh is not evil, nor does it sin of itself. Although the flesh is amoral, it does provide the equipment, the occasion, and the seat for sin if the human will is not constantly assisted by the Holy Spirit. But a person born with sinful flesh need not be a sinner.
19
It has been frequently observed that the New Testament presents a very uncomplicated, straightforward understanding that Jesus was a man in every sense of the word.
20 True, New Testament writers remembered Him as possessing much more than human significance: They reverently referred to Him as God who became man. But their witness to Jesus does not suggest that they thought of Him as having physical, emotional, or moral advantages not available to His contemporaries.
At Pentecost, Peter simply called Him “ ‘Jesus of Nazareth, a Man attested by God to you by miracles, wonders, and signs which God did through Him in your midst’” (Acts 2:22, N.K.J.V.). And Paul says Jesus Christ “was born of the seed of David according to the flesh” (Rom. 1:3, N.K.J.V.).
New Testament support
Nowhere in the New Testament do we get the slightest impression that Jesus visited earth in some kind of heavenly space suit that insulated Him from the risks inherent in a sin-permeated world. Let us examine some of the New Testament references to our Lord’s humanity to see whether this observation can be supported.
A.
The virgin birth (Matt. 1:16, 18-25; Luke 1:26-38; 3:23). The fact that one human parent was organically involved in the birth of Jesus is sufficient to indicate His indebtedness to human heredity. To suggest that He was born free from the liabilities of heredity is to go down the same road that Roman Catholicism started upon when it confused sin with physical substance. After this confusion, the doctrine of the Immaculate Conception became a theological necessity. In turn, that doctrine led to the assumption that Christ took a pre-Fall human nature.
No Biblical evidence suggests that the stream of human heredity was broken between Mary and Jesus. The burden of proof lies with those who believe (1) that there was a physical break in the heredity stream between Mary and Jesus and (2) that because of some special insulation, He was “exempt” (a familiar word in Roman Catholic theology) from the full liability of fallen human nature.
21 Some refer to Luke 1:35 as if that text conclusively indicates Christ had a pre-Fall nature. (See various English translations, such as the R.S.V.) But Luke is not discussing our Lord’s human nature. He simply states that Christ’s holy character would always distinguish Him as our sinless Saviour.
B.
The Son of man (Matt. 8:20; 24:27; et al.). In this self-description, Jesus declared His identification and solidarity with mankind. The second Adam is not a special creation or a clone of the first—He is a hereditary descendant, born of a woman. Only by assuming the same fallen nature shared by those He came to save could He truly be the Son of man.
C.
The Adam/Christ analogy (Romans 5; 1 Corinthians 15). This first/second Adam analogy seems to be one of Paul’s significant theological motifs. The analogy is often considered Paul’s counterpart to our Lord’s self-identification, Son of man. In brief, it seems to suggest most strongly the solidarity and identification of both Adam and Jesus with the human race. In Adam we have the head of sinful humanity, and in Jesus, the head of the overcomers, humanity that conquers all temptations.
22
Many consider Romans 5:12 as evidence that men and women are born sinners, but such is not Paul’s argument. He is simply stating an obvious fact—the stream of death began with Adam. But Adam’s descendants all die “
because all men sinned.”
All men and women are “in Adam” through natural birth, but only those who choose can be “in Christ,” the second Adam. Our Lord has called everyone to be “in Christ,” and only those who frustrate His call will be ultimately lost.
The assumption that Jesus took Adam’s pre-Fall nature seems to destroy the force of Paul’s parallel and his principle of solidarity. Paul’s Adam-Christ analogy becomes relevant to mankind and to the great controversy only if Jesus incorporated Himself within fallen humanity—only if He met sin in the arena where all men are, “in Adam,” and conquered every appeal to serve self, whether from within or without. Jesus intended that those in Him would be united corporately with the results of His saving work. But to accomplish this, He must first have been corporately connected with humanity in its fallen condition.

D.
Paul’s use of sarx. Paul uses
sarx (“flesh”) in a variety of ways,
24 including (1) its ordinary meaning of flesh as a physical feature (1 Cor. 15:39; 2 Cor. 12:7; Col. 2:1); (2) in a metaphorical sense, as that which distinguishes man-kind from God (1 Cor. 15:50; cf. Eph. 6:12) or that which refers to human nature or earthly descent (Rom. 1:3; 4: 1; 8:3); and (3) as a synonym for
sin (chaps. 6:19; 7:18; 8:4).
Paul flees from Hellenistic dualism and does not ascribe to
sarx a substantive evil and sinfulness. Although
sarx is morally neutral, Paul teaches that it does provide the seat and material in which evil may operate. It is the place where self-indulgence is expressed. Christians, though living in physical flesh (
sarx), should no longer allow sin to rule their
sarx (flesh); the Spirit provides power to the committed believer who chooses to control the desires that naturally arise in
sarx. (See chap. 8:3-9.)
At times Paul uses
sarx as a synonym for
sin. And his doctrine of sin is as deep as his doctrine of creation is high. But he always keeps sin on the personal level, as a fractured personal relationship or an act of a responsible person (cf. James 4:17). The results of sin—fallen human nature— are given to all men and women at birth. But no one is held personally guilty or responsible for that fallen human condition (
sarx).
E.
“The likeness of sinful flesh” (Rom. 8:3). Here we find Paul using words with great care. He states clearly the perfect sinlessness of Jesus. But he also emphasizes that our Lord overcame in the same sinful flesh (
sarx) that since Adam all men and women have inherited. Paul’s message: Jesus remained sinless in the arena where sin had conquered all other human beings. In so doing, He exposed the nature and vulnerability of sin.
Anders Nygren commented: “It was to be right in
sin’s own realm that the Son was to bring sin to judgment, overcome it, and take away its power. It is therefore important that with Christ it is actually a matter of ‘sinful flesh,’ of
sarx hamartias.
“Christ’s carnal nature was no unreality, but simple, tangible fact. He shared all our conditions. He was under the same powers of destruction. Out of ‘the flesh’ arose for Him the same temptations as for us. But in all this He was master of sin.”
25
Karl Barth adds that Christ’s perfect obedience in our fallen nature means that “the commission of sin as such is not an attribute of true human existence as such, whether from the standpoint of its creation by God or from that of the fact that it is flesh on account of the Fall.”
26
“In every respect” (Heb. 2:17) He was “in the likeness of sinful flesh”—except that He did not sin. What better way could sin be condemned? How much clearer could Paul have said that possessing “sinful flesh” does not necessarily make a person a sinner? Jesus beat back Satan in sin-entrenched territory, Satan’s home field. Never again need anyone, anywhere in the universe, doubt the fairness of God’s laws or the adequacy of enabling grace and obedient faith.
Perhaps C. E. B. Cranfield, professor of theology at the University of Durham, has said it best. After taking into view all the possible interpretations of Romans 8:1-4, he wrote:
“By
sarx hamartias Paul clearly meant ‘sinful flesh,’ i. e. , fallen human nature. But why did he say
en homoi6
mati sarkos hamartias [“in the likeness of sinful flesh”] rather than just
en sarki hamartias (“in sinful flesh”]?”
27
Cranfield summarizes five answers that have been suggested: (1) Paul did not wish to imply the reality of Christ’s human nature. (2) He wanted to avoid implying that Jesus assumed fallen human nature. Jesus really took flesh, but it was only like, and not identical with, our flesh. (3) Paul used
homoi6
ma to indicate that Jesus took our fallen human nature, but it was only
like ours because ours is guilty of actual sin and He never sinned. (4)
Homoi6
ma here means “form” rather than merely “likeness.” (5)
Homoi6
ma here “does have its sense of ‘likeness’; but the intention is not in any way to call in question. . . the reality of Christ’s
sarx hamartias. but to draw attention to the fact that, while the Son of God truly assumed
sarx hamartias. He never became
sarx hamartias and nothing more, nor even
sarx hamartias indwelt by the Holy Spirit and nothing more (as a Christian might be described as being), but always remained Himself” (cf. Phil. 2:7).
28
As to number 1, Cranfield notes that it attributes to the phrase a docetic sense inconsistent with Paul’s thought. And it is contradicted in this very verse (Rom. 8:3) by
en te
sarki. He objects to the traditional answer (number 2) by saying that it “is open to the general theological objection that it was not unfallen, but fallen, human nature which needed redeeming.”
29 In regard to number 3, he points out that
homoi6
ma is related to the nature discussed and not the question of sinning. “The difference between Christ’s freedom from actual sin and our sinfulness is not a matter of the character of His human nature (of its being not quite the same as ours), but of what He did with His human nature.”
30 As to number 4, he comments that if Paul meant to say this, it is difficult to understand why he did not simply say
en sarki hamartias.
Cranfield says: “We conclude that. . . [5] is to be accepted as the most probable explanation of Paul’s use of
homoi6
ma here, and understand Paul’s thought to be that the Son of God assumed the selfsame fallen human nature that is ours, but that in His case that fallen human nature was never the whole of Him—He never ceased to be the eternal Son of God.”
31
Like Nygren and Barth, Cranfield sees this passage as stressing where the conflict occurred. God’s “condemnation” of sin “took place in the flesh, i. e. , in Christ’s flesh, Christ’s human nature.....
