Since we can never separate Christ from his Church, since the two are one, and since you believe that there is nothing of the Faith or church left in left in Rome (assuming this is what you believe), then you must also believe that Christ is with his church only in the individual trad chapels.
You say that we are not to concern ourselves with the Church's indefectibility or the status of the pope, but if you contend that there is no Faith or Church left in Rome, then it follows that you need to address indefectibility and the pope's status. In my opinion.
Well, what good does it do, what does it profit us to concern ourselves with something (the status of popes and the indefectibility of the Church) we have no need to concern ourselves with - and can do nothing about?
The Church's indefectibility has Christ's promise and should be plenty good enough for all Catholics - if they have faith that is. It is *only* when their faith is very weak or lost that one concerns themself with the indefectibility of the Church, which is Christ.
I just know what I posted and you know it as well, that Rome has been taken over, but that does not mean there is no faith left in Rome at all, what it means to me is woe to all those in charge.
