What Jesus did was no different than what the rabbis did regarding all the other commands in Leviticus, Exodus, and Deuteronomy, though the Jesus movement clearly did emphasize more than the early rabbinic movement certain things (prophethood, wonderworking, and lay ministry) and certain texts (Isaiah) over other things (purity laws, food commandments, beliefs about the nature of sin, the role of the Temple, Shabbat restrictions). These differences in emphases accord with what was happening in the pluralistic context of Jewish thought in Judea and the Galilee during late antiquity more generally (see, e.g., the catalogue of texts at Qumran or the texts contained in the Cairo Genizah).
To say this isn't what's happening and that Jesus was totally divorced from the Judaism he grew up in, identified himself with, and explicitly preached to, is, at best, antinomianism. At worst, it's just cope.
