That looks like a more interesting spelling of secks.

Messianic belief in Jesus was largely consistent with Jewish apocalyptic nationalism, and it eventually thrived in small communities of Jews in Palestine and the eastern Greco-Roman world. In it's first decades, the new faith's most effective advocate was the apostle Paul, whose tireless travels and passionate letters to believers promised them imminent redemption at the hands of a risen Christ.
More importantly, he argued that non-Jews could join the faith without submitting to the male circumcision and dietary restrictions required by traditional Judaism.
