The Church is Apostolic

As you probably know by now, there are four marks of the church: One, Holy, Catholic, and Apostolic. I am going to talk about the church as Apostolic.

The church is Apostolic in that it was founded by the apostles, led by the apostles, and taught by the apostles. Some might say that the apostles are not present today and therefore it is no longer apostolic, yet this is false. There's something called the apostolic succession. Every apostle before they died selected a successor. The apostle might have selected more than one successor. The pope is the successor of Peter the apostle. The Pope has the keys the kingdom and his infallible just asked St. Peter.  Today the successors of every apostle called bishops. Every bishop can follow his linage to one of the apostles.

There can only be a certain number of bishops under the age of 80 at any given time. Therefore they might be over 100 million bishops but there are only 200 under the age of eighty although that is highly unlikely. Bishops currently have the mission that Christ entrusted to the apostles which is to teach, baptize, sanctify, and make disciples of all nations. If a bishop is good with his duties, he might be selected to be a cardinal. A cardinal is a specific type of bishop that is in charge of selecting a new pope. In these reasons, the Church is apostolic.
