I thought it was Bush2 that said "Those who are not with me are against me". 
Jesus taught us to trust and love God. He gave us the Beatitudes and the goal of the Kingdom of God to guide us to Him. He was more interested in old widow who gave 2 pennies than the Temple and its sacrificial system. He also made it clear that He would replace the Temple as direct access to God. He didn't institute a Church or magisterial teachings. There were no doctrines or dogma. The Church created that. He didn't ordain anyone. He called disciples/followers and the Twelve who were his closest disciples. 
I see the role of the Church as a community that follows His Teachings. Everyone in the  community has a conscience to discern the will of God to help guide them to the Kingdom.
