Regarding the existence of the evil side in every individual, Judaism and Christian Science teach two conflicting doctrines. Judaism teaches that the evil side (Heb. yetzer hara) is an essential and non-negotiable part of human makeup:
Rabbi Nahman bar Samuel bar Nachman said in the name of Rabbi Samuel bar Nachman: ... "And behold it was very good" (Genesis 1:31) - this refers to the yetzer hara. But is the yetzer hara indeed very good?! - Were it not for the yetzer hara, a man would not build a home, or marry a woman, or have children, or engage in business.
Mary Baker Eddy, in Science and Health with Key to the Scripture, says that human nature is a logical system, and the presence of any sort of evil side in a human being will eventually lead to the entire human being becoming evil (ex falso quodlibet) Quote:
If man is constituted both good and evil, he will end in evil. An error in the premises must appear in the conclusion. To avail yourself of the power of the Spirit, you must depend on no human reliance.
Which one is closer to traditional Christian doctrine?
