Jesus never "established" a church of any type at all - you have to pin the blame for that one on orthodox Christians centuries later with the huge help and influence of the Emperor Constantine (306-337 A.D.).  In Jesus' day, the pharisees and Jews, certainly the Romans, were not exercised about any "church" - they had political agendas to protect which Jesus threatened.  Jesus was only interested in a "kingdom of God" best defined in the Beatitudes.

It is in Paul's writings that the seminal ideas of church emerge for the first time.  Paul rather than Jesus is more accurately considered the "founder" of Christianity.  The church that emerges in the New Testament is one that is not only democratic and charismatic but down right socialist [check out Acts].  Only after Constantine imposed an "imperial" model on Christianity did we begin to see Jesus artistically depicted as a king rather than as a carpenter's son.
