St. Gregory Nazianzen explains the current disaster in the Church’s human element
More than 1600 years ago, St. Gregory Nazianzen, Doctor of the Church, warned us that the human element of the Church suffers shipwreck when She has evil bishops. Here are his words:
The light and eye of the Church is the Bishop. It is necessary then that as the body is rightly directed as long as the eye keeps itself pure, but goes wrong when it becomes corrupt, so also with respect to the Bishop, according to what his state may be, must the Church in like manner suffer shipwreck, or be saved.
As the Catholic Church’s bishops go, so go their flocks. With the spectacular betrayal by the Church’s bishops beginning with Vatican II, it is no wonder that their flocks suffered the shipwreck of heresy and vice, following their bishops!
With the more recent, spectacular betrayal of the bishops consecrated through Archbishop Lefebvre – who are supposedly faithful to Catholic Tradition – it is no wonder that their flocks are suffering the shipwreck of liberalism, compromise, and laxity, following their bishops (e.g., accepting 95% of Vatican II and countless other evils)!
 Words of St. Gregory Nazianzen quoted in the Catena Aurea on St. Luke’s Gospel, St. Thomas Aquinas, editor, explaining Our Lord’s words:
The light of thy body is thy eye. If thy eye be single, thy whole body will be lightsome; but if it be evil, thy body also will be darksome.
St. Luke’s Gospel, Ch. 11, v. 34.

Bishop Williamson’s group is not better but is liberal in a somewhat different way. See, e.g., https://catholiccandle.neocities.org/priests/williamson-the-evil-of-comfortably-tolerating-heresy.html
