Marcus Grodi and Msgr. Jeffrey Steenson continue on to Book 3, Section 3 of Against Heresies by St. Irenaeus of Lyons, and talk more about the importance of listening to the right voices.

St. Irenaeus reminds us that the reason the people in his day should trust their leaders is because they were appointed by the successors of the apostles, who were appointed by the apostles themselves, and goes on to list the pedigree of the successors of Rome in order to illustrate their importance.
