CIC 888 Bishops, with priests as co-workers, have as their first task “to preach the Gospel of God to all men,” in keeping with the Lord’s command.1 They are “heralds of faith, who draw new disciples to Christ; they are authentic teachers” of the apostolic faith “endowed with the authority of Christ.”2
