From Korah and his company, that strange portentious cry is sent.
A Levite priestly power he sought, And Aaron, saint of God, opposed:
Her prey the opening earth has caught, And o'er the rash intruder closed.
~ Richard Mant, Bishop of Down & Connor
St. Jude connects the account of the sons of Korah from Numbers 16 with Schism from the Catholic Church.
"But I want to remind you, though you once knew this, that the Lord, having saved the people out of the land of Egypt, afterward destroyed those who did not believe." (Jude 1:5) "Likewise also these dreamers defile the flesh, reject authority, and speak evil of dignitaries." (Jude 1:8) "Woe to them! For they have gone in the way of Cain, have run greedily in the error of Balaam for profit, and perished in the rebellion of Korah." (Jude 1:11)
The second century Apostolic Father, St. Ireneus of Lyons wrote that Christian tradition is "derived from the apostles, of the very great, the very ancient, and universally known Church founded and organized at Rome by the two most glorious apostles, Peter and Paul; as also by pointing out the faith preached to men, which comes down to our time by means of the successions of the bishops. For it is a matter of necessity that every Church should agree with this Church, on account of its pre-eminent authority, that is, the faithful everywhere, inasmuch as the apostolical tradition has been preserved continuously by those faithful men who exist everywhere." (Against Heresies III, 3:2)
