If a priest can't decide on his best position on the Pope question during 6 years at a seminary and/or years at a monastery, what was he doing during all that time? Playing tiddly winks?
Usually a Seminarian has LESS time for consideration and study after Ordination, not more.
It's a priest's JOB to study and learn his Faith, as well as the Crisis in the Church. Ignorance has no place in a priest. There are only so many positions one can take on the Pope question, and they are all mutually exclusive. And each will appeal to a given type of person, based on what they focus on, their history, temperament, training, etc.
One can change over time as the world, or one's understanding, changes. I understand things change, people learn more, consider things a different way, Popes die and new ones get elected, the Crisis in the Church gets worse or better, etc. but that would justify a change after YEARS, not months or weeks after ordination. Pope Francis was still Pope last December when Father was ordained. Pope Francis was just as bad then as he is today. The same arguments can be made for including (or removing) his name from the Canon last December as well as today.
One can also change for less noble or even base reasons. I just think it's ridiculous when a priest is a member of the SSPX for 10, 15 years and then they leave to join the FSSP because "they just realized -- *gasp* -- the SSPX is in schism!" It doesn't speak well of the intellect of said priest, right? But in reality, such a priest is simply getting old and wants to try something new, or he wants more creature comforts, is weary of The Fight, etc. so it all makes sense. So in such a case, there is no reason to believe he deceived his superiors from the beginning.
But when you have priests that get ordained and then IMMEDIATELY (say, in single-digit months) leave for another position or group, you really have to question the sincerity (and/or stability) of the priest to begin with.
I'm sure this happens frequently, but the only other case I can remember off hand was the Society of St. John in the late 90's. Several supporters of the SSJ kept quiet until ordination, then they immediately left and joined their brethren on the SSJ commune. And I think some of the sedevacantists in 1983 who split from the SSPX did this as well -- kept quiet until they were safely in Holy Orders.
A man who would "steal" the priesthood this way, sneaking into the sheepfold by another way -- there are no words. What a curse he brings on his priesthood, rather than a blessing, when he begins his very priesthood with an act of deceit, aimed at the very bishop ordaining him! Our Lord is Truth. Anything of untruth or lies comes from the father of lies, the devil himself.
Now it's possible this doesn't apply to Fr. Da Silva, but if not, then it means he's flaky and unstable, or headstrong and allergic to obedience. Are these options any better?
See the "anti-sedevacantist" video he posted just a few weeks ago! What has changed in the Church since then early July, or last December? NOTHING. Only Fr. Da Silva's spinning head has changed, which has now landed again and happens to face in a new direction. What will his position be next week?
There are only a few possibilities to explain Fr. Da Silva's recent behavior:
A) Deception, hiding his true position before his ordination
or
B) He is unstable to a troubling degree. (What next? He'll join a conclavist group? Get consecrated bishop or elected Pope? Go back to the Novus Ordo or maybe join the FSSP?)
C) The Una cuм issue is just a side-issue or even an excuse; a mere symptom of an "independent streak" he has developed (or decided to reveal), which will give him the excuse to have no Bishop over him.
There aren't any other options, unless you count combinations of A), B), and C.
But none of these options do any credit to Fr. Da Silva!
I invite CentroAmerica or any other of Father's close friends to explain to all of us what happened.
If I'm wrong, please explain how I'm wrong.
P.S.
I don't know Fr. Da Silva at all; I only know the facts of this case, which I am discussing here in a rational and logical manner.
