The Third Mark: Catholic

The Church is catholic. Saint Ignatius of Antioch in his letter to the Smyrnaens, which my classmates and I had to read earlier this year, used the word catholic, meaning universal, to describe the Church. The Church is catholic because Christ is universally present in the Church. Christ told His Apostles to spread his message to "Jerusalem, throughout Judea, in Samaria, and to the ends of the earth" (Acts 1:8). Christ told his Apostles to evangelize the world by saying "Go therefore and make disciples of all nations" (Matthew 28:19). These quotes show the universality of the Church because Christ is telling his Apostles to spread the word of God to everybody all the way to the ends of the earth, so that everybody could hear the Good News of the word of Christ.
The picture shown in this post is the symbol of the Pope. I chose this picture to symbolize the third mark of the Church, Catholic, because the Pope, the successor of Peter, is the head of the Catholic Church. He continues the mission of the the Apostles, along with the Bishops, to evangelize and to spread the word of Christ to the ends of the earth. With Papal infallibility, the belief that God protects the Pope from error when teaching on matters of faith and morals, the Pope is able to spread the message of Christ message throughout the world as Christs intended it.
