Canon 1373 that Mr. Stine quotes is found at this Vatican link. Yes, an operative word here is "just" but so is "incites animosity or hatred". There motive is ascribed to the person(s) facing interdicts. Aside from the pope's famous "who am I to judge" quip, any progressive thug in the Vatican would soon find himself skating thin ice to bring about any such action against faithful Catholics (Your Truly included) who are merely calling a spade a spade.
Mr. Stine rightly reminds us that we are in fact obliged, under pain of sin, to refuse compliance with unjust and/or immoral dictates from Church hierarchy - including those who are vindictively trying to throttle the Traditional Latin Mass. Speaking of "inciting hatred or animosity", are Vatican officials willing to place themselves under said interdicts for thumbing their noses at Pope St Pius V and what he proclaimed in Quo Primum? By the way - in case some might think that Traditionis Custodes now overrides Quo Primum, not so. TC is a moto propitio while QP is an Apostolic Constitution in the form of a papal bull. The latter is the more solemn and binding document by far, thus Traditionis Custodes does not override it.
So, my fellow bloggers, what do we do now? Simple. Continue to shine the light on the cockroaches infesting Holy Mother Church. We do not blink, we do not cower. We know very well that we speak ot uphold the Church. It is the progressives in the Vatican and chanceries that are "inciting hatred and animosity" against Sacred Tradition and Jesus' teachings. We stand firm. Should any such decree come our way, we shine the light on that and give it the treatment that it deserves, as Mr. Stine mentioned in his clip. This will be a struggle but we cannot flinch.
