"He was born an Orthodox Jew"

Orthodox Judaism favours a strict interpretation of, and adherence to, the laws set out in the Talmud. Orthodox Jews are supposed to observe several core practices and are prohibited from certain sexual practices, amongst them adultery and homosexuality.

It has already been suggested that Elgin is a masochist, and we later find out that he uses prostitutes, thus committing adultery. Since we do not know the gender of the narrator we cannot tell whether or not his/her relationship with Louise is a homosexual one, and therefore whether Elgin's reaction to it is further affected by his religious beliefs.
