Mystical Body of Christ has:
Spiritual/Invisible Aspect
The Spiritual/Invisible aspect of the Mystical Body of Christ
Physical/Visible Aspect
Christ established the Church with visible hierarchy
Put apostles in charge
Physical Church carries on Jesus' teachings and actual work that he did
Pope is Peter's successor--> Vicar of Christ
Vicar = someone authorized to act in the name of another
The Apostles appointed bishops, who in turn appoint other bishops which means that the teaching authority of the Church comes from Jesus
"When Christ instituted the Twelve, 'he constituted [them] in the form of a college or permanent assembly, an the head of which he placed Peter, chosen from among them.' Just as 'by the Lord's institution, St. Peter and the test of the Apostles constitute a single apostolic college, so in like fashion othe Roman Pontiff, Peter's susccessor, and the bishops, the successors of the apostles, are related with and united to one another.'" (CCC 880)
The Mystical Body of Christ much represents the life of the Individual person. The Mystical Body of Christ has a Spiritual aspect. The individual has a prayer life and works to attain friendship with God through that. The mystical Body of Christ also has a Physical aspect. The Individual obviously has a Physical aspect as he is a Physical being. As the Church has a head, so we have a Physical head, as we have parts, we make up the parts of the Church. As the Church is being passed on, so we pass on our properties to the next generation. So, in reality, its no mystery that we make up the Mystical Body of Christ. We all have many traits that link us to it.
