Saar was born and raised in Netanya where he was active in various youth movements. He enlisted in the IDF in 1993 and served as a tank commander in the armored corps school in the south. The assassination of Yitzhak Rabin was a turning point in his Jewish identity, and he began to study. Saar has a BA from Tel Aviv University in general history and classic studies, where he met his wife Sharon. In the late 90’s he began to work with Beit Daniel, the Center for Progressive Judaism in Tel Aviv and entered the Israeli rabbinical study program, and was ordained as a Rabbi in 2004. He believes that “The modern age is characterized by alienation and estrangement. Feelings of fellowship, fraternity and loving kindness can heal this ailment”. He believes in Judaism that is contemporary, accessible, up to date, and innovative.
