Was the Roman Catholic Church the head of Judea when Jesus was cruicfied?
There was no Roman Church when Jesus was crucified. Christ was
the beginning of Christianity. After He died and ascended to the
Father it was left up to the Apostles to carry on the new
faith.
Matthew 16:18 And I say also unto thee, That thou art Peter, and
upon this rock I wil build my church: and the gates of hell shall
not prevail against it.
