Could Vatican II be repudiated?

July 16, 2020 (Rorate Caeli) — On his blog Settimo Cielo of July 13, the Vatican reporter Sandro Magister was highly critical of Bishops Carlo Maria Viganò and Athanasius Schneider, hurling an accusation at them for spreading “fake news”. *

The term “fake news” was used also in reference to Monsignor Schneider’s theses, whereby the Church, in Her history, has corrected doctrinal errors committed by precedent ecumenical councils, without, in this manner, “undermining the foundations of the Catholic faith.” Magister accuses Schneider of historical incompetence, citing, as evidence, a brief intervention by Cardinal Walter Brandmüller on the Council of Constance, which in reality refutes nothing of what was affirmed by Monsignor Schneider.

The facts are these. On April 6, 1415, the Council of Constance issued a decree known as Haec Sancta 1, wherein it was stated solemnly that the Council, assisted by the Holy Spirit, received its power directly from God: hence every Christian, including the Pope, was required to obey it. Haec Sancta is a revolutionary document which raised many questions as it was first interpreted in continuity with Tradition and, subsequently, reprobated by the Pontifical Magisterium. It had its coherent application in the decree Frequens, of October 9, 1417, which called for a Council five years later, after seven years another one and then one every ten years, de facto attributing to the Council the function of a permanent collegial body, alongside the Pope and de facto superior to him.

It's also worth noting that Rome accepted, and then two centuries later repudiated the Eighth OEcumenical Council  (Constantinople 879-880).
