Hi DB ,
Christianity ( or at least what is called such ) is probably the most varied in what individuals ( groups + persons ) believe of all the major religions ... likely due to the fact that it largely emphasizes humanity's freewill and Salvation via God's mercy + grace .
This tendency to be diverse or varied is in some ways a plus ( stimulates individual study , analysis , and critical thinking rather than blindly following doctrine or tradition ) and in other ways is more of a minus ( tends to promote considerable disagreement , dissent , and disunity ) . [ Personally , think the divisions are less evil than being under coercive dogma .]
But what is being gotten at is this - There is certainly a myriad of different views , opinions + beliefs concerning the Jews and their role /place under God , amongst those considering themselves followers of Christ / The Christian religion .
Overall , there's likely a more favorable impression towards Jewish folks in Christianity than there is in Islam ... but some who claim to be Christian have been known to spue out vitriol against Jews .
The emphasis which stands out to me is that - God is no respecter of persons , and each of us , whether Jew , Jamaican , or Jesuit , is judged or evaluated by what goes on in our heart and how we live our life .
Then Peter opened his mouth, and said, Of a truth I perceive that God is no respecter of persons:
But in every nation he that fears him, and works righteousness, is accepted with him. <-----> Act 10:34+35
For as many as are led by the Spirit of God, they are the sons of God. <-----> Romans 8:14
For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
For whosoever shall call upon the name of the Lord shall be saved. <-----> Romans 10:12+13
Generally , with any large group of people there is a variety of folks , some more honorable + praiseworthy than others , consequently it's not right to lump everyone into a single category based on a broad-based association , such as race , religion , political party , or any other largely man-made label placed over and upon individuals .
For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:
But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God. <-----> Romans 2:28+29
In it's purest application a Jew is a person whose life radiates the praise of God through loving right and hating wrong as Jesus did + does .
Jew comes from Judah , Judah means praise , specifically of God .
Hope this is helpful to you !
