The fact that you know that they are two seperate things shows you already know something about it. Biblical Judaism, based upon the sacrificial system found in Dueteronomy and Leviticus, ceased to exist with the destruction of the Jerusalem temple by the Romans in 70 AD. No temple, no Jewish priesthood, no sacrifice. Christ’s once for all sacrifice on the cross, now remembered sacramentally on the altars in Catholic churches, has replaced this system.
The Jewish temple culture was suplanted by rabbinical Judaism which is synagogue based. It was was developed by the Pharisee school after the destruction of the temple. It is based less on ritual, and more on ethical monotheism and in passing on the traditions of Judaism.
