Meaning, its seriousness on several levels cannot be overstated.
On Friday morning, each and every Catholic bishop in the world will need to rise, put on a strong pot of coffee, read the Exhortation, and make a series of decisions which will directly affect the vector of many, many souls, foremost his own.
He must decide whether or not his diocese will endorse the sacrilege, which presumably would entail erecting structures and programs to circumvent the reality of Matthew 19:9. If he chooses to not overtly endorse it, but rather stay quiet and do nothing, well, that’s nearly the same thing as endorsing it. Inaction is action.
Or he could publicly denounce the document and call out its authors and endorsers. How many will?
Beyond the particular issue at hand, Communion for those guilty of obstinate unrepentant mortal sin, and the horrific sacrilege being demanded from bishops and priests, we have another problem. Leaving the solutions up to each individual diocese isn’t collegiality, it’s anarchy. Have these people learned nothing from the Anglicans?
Matters of Faith and Morals are the Truth itself. Truth cannot vary from diocese to diocese. This is third grade catechism.
Pray intensely for your bishop. Pray for your priests. War is coming.
