The largest Reform congregation in North America.
Temple Israel was founded in Detroit in the summer of 1941. Within sixty days there were nearly 600 members. As the city’s Jewish population moved north and west the Temple moved to a new campus in 1980 and further expanded its building in 1989.
According to Wikipedia “Temple Israel is among the largest Reform congregations in the country. As of 2012 its website states that it is the largest in North America, and the official database of the Union for Reform Judaism confirms this, reporting a membership of 3,383. In 1995, Temple Israel was the first reform congregation to open a mikveh (ritual bath).”
