"The Pharisaical "sect of the circumcision" believed that NO commandment of the Torah could be kept while uncircumcised in the flesh. Traditionally, the circumcised could not even enter the home of uncircumcised Gentiles."

I don't think this is an accurate assessment of Pharisaic beliefs. They actually taught that certain commandments of the Law were mandatory for the Nations to keep and they called these the Noahide Laws.
