Today the Church celebrates the feast of St. Matthias, arguably the least known of the Apostles. While not one of the original 12 chosen by Our Lord, Matthias was elected as a replacement for Judas after he committed suicide. You can read all about his election in Chapter 1 of the Acts of the Apostles (click HERE).
One of the most important principles that this Bible passage illustrates is that of Apostolic Succession. It serves as proof that The Lord (speaking through Peter, the first pope) intended for the apostolic ministry to be continued throughout the ages. To this day, the Catholic Church remains faithful to His wishes by the election of bishops, the modern day successors to the Apostles.

We’re still doing things the same way 2000 years later!
