I'm not on board that he's a mason or part of a conspiracy, but I do have to wonder whether Vigano's eulogy for Ratzinger helped move Novus Ordites/indult Conciliars towards Catholic Truth or remain in the Conciliar sect. Given the attacks I've already seen (elsewhere) from those NO's/indulterers who are pro-Benedict and Vigano, I've got to think it more likely the latter.
Its rather like when we say someone "acted out of character."
Yes, he did it, but it represents a departure from his normal way of acting (or in this case, from his normal good and traditional doctrinal acuмen).
Every writer has that happen at some point (even here on Cathinfo, a stalwart traddy goes off and says soemthing sentimental or even liberal). It doesn't mean that person has gone to the left, or revealed secret liberal tendencies. It could be explained by 1000 different causes (laziness, fatigue, strong emotion, etc.).
None of that would suffice to recharacterize the positions attributed to such an one, because the exception does not disprove the rule, and a man is said to believe that which he most frequently teaches, not what appears as an anomaly to contradict what has been said before (and especially after) such anomalies.
