But Jesus tells us (and the pope and bishops) what we’re supposed to be teaching:
Matthew 28:19-20 (KJV) 19 Go ye therefore, and teach all nations...20 Teaching them to observe all things whatsoever I have commanded you...
I agree.
BUT: Even though we are all called upon to be a witness and to spread the word and all that, when it comes to doctrinal disputes and the authority to decide between right and wrong doctrine, that falls to the bishops.
That is what the great councils were all about. In fact, the fist council is actually in the Bible, in Acts, the
Council of Jerusalem. Long story short, everyone was arguing about whether or not Christians have to be circumcised. The council, with Peter, among them, decided that Christians do
not need to be baptized. They exercised their authority to "bind and loose", and ever since then, Christians have not needed to be circumcised.
The councils that followed are:

Decisions: Condemned Monothelitism, which held Christ had but one will, the divine (this heresy arose as a reaction to the monophysite heresy); censured Pope Honorius I for a letter in which he made an ambiguous but not infallible statement about the unity of operations in Christ (an episode commonly used by anti-Catholic writers as an argument against papal infallibility, but for the real meaning, see Catholicism and Fundamentalism, pages 227-229).
Nicaea II, 787 AD

Pope Hadrian II, 867-872
Emperor Basil, 867-886
Decisions: Recondemned Adoptionism; deposed Photius as patriarch of Constantinople, thereby ending the Photian Schism, but this did not completely remove disaffections between the West and the East (in 1054 came the final break, when the Eastern Orthodox Churches broke away from unity with Rome).

Pope Callistus II, 1119-1124
Emperor Henry V, 1105-1125

Ripley, page 27); condemned Waldensianism and Albigensianism, a form of Manichaeanism (an ancient heresy that held that matter is evil; Albigensians opposed the authority of the state and of the Church, opposed the sacrament of matrimony, and practiced ritual suicide; despite these tenets, many anti-Catholics believe Albigensianism was the continuation of “real Christianity” during the Middle Ages and was a forerunner of Protestantism).
Lateran IV, 1215 AD
Pope Innocent III, 1198-1216
Emperor Otto IV, 1209-1215

Decisions: Ended the Great Schism, which involved three rival claimants to the papacy (see in this issue the article by Canon Francis J. Ripley, page 27); opposed the teachings of John Wycliffe, who taught sola scriptura, denied the authority of the pope and bishops, denied the Real Presence of Christ in the Eucharist, and wrote against penance and indulgences; condemned as a heretic John Huss, who denied papal authority and taught wrongly about the nature of the Church and who was burned at the stake in 1415 (in 1457 his followers established what became known commonly as the Moravian Church, which was the first independent Protestant church).
