Herodion of Patras (also Herodian or Rodion; Greek: Ἡρωδίων, Ἡρωδιανός, Ῥοδίων) has been thought by some to have been a relative (συγγενής) of Saint Paul, as in a greeting Paul calls a Herodion a sungenēs in Romans 16:11.
But Paul uses the term συγγενής (sungenēs) for fellow Jews in Romans 9:3.
So συγγενής (sungenēs) can mean relative even as broadly as fellow Jew.
After beating, stoning, and stabbing him; they left him for dead, but St. Herodion arose and continued to serve the Apostles.
His feast days are celebrated on January 4 among the Seventy, April 8, and November 10.
