Seriously? Why do you think that Christians refer to the Judeo-Christian ethics and values?
If we read the Christian scriptures, we see that the Christian leader made a couple of egregious misquotes of the Jewish scriptures. None the less, he did say a few really worthwhile things. However, it turns out that these things were lifted from the Jewish scriptures and presented as if original to Jesus in the Christian scriptures.
Here are just a few of many concrete examples:
'but the humble shall inherit the earth, and delight in abundant peace"
becomes in Matthew 5:5 (the sermon on the mount)
‘Blessed are the meek, for they shall inherit the earth’
“Who may ascend the mountain of Hashem and who may stand in the place of sanctity?One with clean hand and pure heart;”
becomes in Matthew 5:8
“Blessed are the pure in heart, for they shall see God”
“Let one offer his cheek to the smiter, let him be filled with disgrace”
becomes in Matthew 5;39
“…but if anyone strikes you on the right cheek, turn to him the other also…”
