Whatever your taste in Judaism, New York has something to offer:
Orthodox
Implies meticulous observance of Jewish law. The Orthodox spectrum is split on issues such as secular education, the role of women, and the ideal balance between work and Torah study
Reform
Anglicization of synagogue services, mixed seating for men and women, and radical disassociation with traditional religious practice
Conservative
Claiming an affinity for tradition without feeling bound by it, Conservative Judaism rejects the divine origin of Jewish law
Reconstructionist
An egalitarian movement that sees Judaism as an evolving civilization in which halacha is not binding and God is largely out of the picture
