Who gave the Catholic Church divine authority to teach?

Jesus Christ gave the Catholic Church divine authority to teach when he said, "Go therefore, make disciples of all the nations".

Explanation

The authority of the Catholic Church does not come from human wisdom, political power, or popular opinion. It comes from Jesus Christ Himself. Before ascending into Heaven, Christ commissioned the apostles to teach all nations, baptise believers, and hand on everything He had commanded. This mission did not end with the death of the apostles but continues through their successors, the bishops, united with the Pope. The Churchs teaching authority exists to preserve and faithfully explain the revelation entrusted to it by Christ. Catholics believe that when the Church officially teaches on matters of faith and morals, the Holy Spirit assists her so that the Gospel may be transmitted accurately from generation to generation. This divine mission gives Christians confidence that the Church remains a trustworthy guide in matters concerning salvation and the Christian life.
