And when it was day, he called unto him his disciples: and of them he chose twelve, whom also he named apostles;

These twelve Christ chose as individual companions and domestics. To these he committed the charge of founding and governing his Church. He sent them as legates, or ambassadors, (for this is the import of the word apostle) to all the world. Hence their power was more universal than that of bishops, which is confined to their own dioceses or districts. The jurisdiction of the apostles was not limited to place. (Tirinus)
This power which Jesus Christ delegated to his apostles, and which was for the benefit and regulation of the universal Church in all future ages, the apostles, in their turn, delegated to their successors in the ministry, with such regulations and limitations as have been judged in the Holy Spirit necessary for the proper government of the spiritual kingdom of God upon earth. And it is the height of presumption to question any ordinations that come to us with the authority of the Catholic Church: for, "whatever the Church says, is true; whatever she permits is lawful; whatever she forbids, is evil; whatever she ordains, is holy; whatever she institutes, is good. "(St. Augustine)
How futile then is the objection of Calvin, who pretends, that an apostle, being nothing but a legate, can make no laws, nor prescribe or teach any thing not expressed in his man datum! (Calvin, Institutes lib. iv. chap. 8)
