To Joseph, please let us know where this Chasam Sofer is that mentions Jews being physically different than non-Jews. Thank you.
onlyemes:
The Gemara suggests that the Shichvas Zera of a Nochri has different
properties from that of a Jew, since the Nochri eats non-Kosher foods and
is physically affected by his diet.
The CHASAM SOFER (Teshuvos YD 175) writes that this Gemara is relevant in
practice. He rules that we cannot assume that a medical treatment that was
tested successfully on a Nochri will also be successful on a Jew.
Rav Elyashev shlita pointed out that the Chasam Sofer writes that the physical characteristics of a Yid are different than a Goy, and that what applies to one may not apply to the other. Therefore, said Rav Elyashev, how much more so regarding the mind/soul?
Always remember: we are superior.
