1. This is a short epistle, but an example of Christian doctrine, in which all the things that a Christian needs to know and live are so masterfully written.
2 First, he teaches what kind of man a bishop or pastor should be, namely, one who is pious and learned to preach the gospel and to destroy the false teachers of works and the laws of men, who always fight against the faith and deceive the consciences from Christian freedom into the prison of their works of men, as if they were supposed to make people pious before God, which are of no use.
In the other chapter, he teaches all classes, old, young, women, men, masters and servants, how they should conduct themselves as those whom Christ acquired for ownership through his death.
In the third, he teaches to honor and obey the worldly rulers, and again calls attention to the grace that Christ has purchased for us, so that no one may think that it is enough to be obedient to the rulers, since all our righteousness is nothing before God. And commands to avoid the obstinate and heretics.
