8.18. If the Church has no pope, how can we have unity in doctrine and avoid chaos and division?

True doctrinal unity is not founded on mere office, but on fidelity to the Deposit of Faith. The Pope’s role is to guard and transmit what Christ handed down—not to innovate or alter it. When someone claiming the papacy teaches heresy, he severs himself from that divine office (cf. Pope Paul IV, Cum Ex Apostolatus Officio).

Sedevacantists are not divided on doctrine—we are unified in the unchanging teachings of the Church up to 1958, the year Pope Pius XII died. While there may be differences in practical matters (as happened even among saints), we are not inventing doctrine, unlike the Vatican II Church which contradicts itself across dioceses, bishops, and conferences. Unity in truth is far more important than false unity under error.
