Authority

Jesus called to him his twelve disciples and gave them authority...
Mat.10:1

Jesus' first act on forming the Church was to give it authority.

Recognising authority seems to invoke faith, faith in the one who gives that authority. The Centurion's great proclamation of faith started with, "I too am a man under authority." 

I believe authority is one of the primary differences between Protestant and Catholic churches. The Protestant Church invites me to have an opinion about doctrine. The Catholic Church invites me to believe... believe in the God given authority of the Magisterium of the Catholic Church. 

I don't trust my opinions. I do trust the Church's teaching authority of the Magisterium. This authority is a strong foundation from which to "Go and make disciples of all nations."

Jesus, I place my trust in you.
