The Center for Jewish–Christian Understanding and Cooperation or CJCUC is an educational institution at which Christians who tour Israel can study the Hebrew Bible with Orthodox rabbis and learn about the Hebraic roots of Christianity. The center was established in Efrat in 2008 by Rabbi Dr. Shlomo Riskin, who has been described as "the most prominent rabbinic spokesperson to Christian Zionists". CJCUC partners with major Christian interfaith organizations such as Christians United for Israel and the International Christian Embassy Jerusalem. Since Riskin's retirement as president of Ohr Torah Stone in 2018, the overseeing of all CJCUC activities has been turned over to David Nekrutman who has served as the center's chief director since its inception.
