Seems to be, would be correct way to consider it. If one considers that as a valid argument, one would just be using the same evidence that the Jews would use against Christains, it is the same as saying that the Christains mislead the Jews.
Both Faiths teach acceptance of Christ and I also see they teach acceptance of the Word of God. The waters are somewhat muddied in the interpretaion of the Quran, but to a Baha'i faith in Jesus as the Christ is immovable.
Luckily the judge for ones heart, is God and we do not have the right to judge another's heart. Christ tells where to look and Christ mentions good fruit, from good trees.
There was one Jesus with a Message of the One God. As believers in Christ, we are one and Christ said the Name will also be One, but Christ did say it will be a new name. The Jews can also argue a common theology, has it served them with wisdom?
A Christain accepts the Old Testament, it became part of faith in Christ.
The question then is, do Christains follow all the laws and practices and all Jewish Theology of the Old Testement?
If not, as one can see, it is not a valid argument, as it has also been used in the past against Christains.
That the events in Jesus life, as the Christ, are seen with a different frame of reference, this in turn does not diminish their importance or beauty.
The Christains will have this same comparison with the Old Testament. A Christain would see a fulfillment of the Old Testement and as such see they have a great love for it, that a Jew is just yet to accept.
Thus again an argument that is on shaking foundations.
It may be best if we share our love for Christ and put theology aside, Baha'u'llah offered;
"Know thou that when the Son of Man yielded up His breath to God, the whole creation wept with a great weeping. By sacrificing Himself, however, a fresh capacity was infused into all created things. Its evidences, as witnessed in all the peoples of the earth, are now manifest before thee. The deepest wisdom which the sages have uttered, the profoundest learning which any mind hath unfolded, the arts which the ablest hands have produced, the influence exerted by the most potent of rulers, are but manifestations of the quickening power released by His transcendent, His all-pervasive, and resplendent Spirit.
We testify that when He came into the world, He shed the splendor of His glory upon all created things. Through Him the leper recovered from the leprosy of perversity and ignorance. Through Him, the unchaste and wayward were healed. Through His power, born of Almighty God, the eyes of the blind were opened, and the soul of the sinner sanctified......"
