Indeed! And we still have some of them hanging around.
You foolish Galatians, who has bewitched you, before whose eyes Jesus Christ was publicly portrayed as crucified? This is the only thing I want to find out from you: did you receive the Spirit by works of the Law, or by hearing with faith? Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh? Did you suffer so many things in vain—if indeed it was in vain? So then, does He who provides you with the Spirit and works miracles among you, do it by works of the Law, or by hearing with faith? (Galatians 3:1-5)
