Then, having prepared everything to be carried on the way, Tobias said goodbye to his father and mother, and they both walked together. With the Lord appearing in the flesh, all things that pertained to the redemption of the world and by which the faith and life of the holy Church would be nourished and strengthened, until the end of the way of this age, were prepared; that is, his virtues, doctrine, temptation, passion, resurrection, ascension, sending of the Holy Spirit, faith of believers, and persecution by unbelievers. Having accomplished these in Judea, the Mediator of God and men preached through the apostles to the people and the synagogue, from whom he had taken the origin of the flesh, the joys of heavenly salvation and peace. And to those who wished to believe and receive, he granted these things through himself, and thus he came to the salvation of the Gentiles in those same his teachers.
