You won't address that big picture, so you head right back down to the details and technicalities.
I am addressing the big picture, but you don't like the answer. Our Lady said that 'the Church will be in eclipse'. In other words, the Church will APPEAR to be replaced, to have disappeared, to have gone away. The truth is that the appearance was not true. She was still there, still shining, had not changed.
Much like the V2 'church', which APPEARS to have violated indefectibility, I say that technically, it did not. Appearances can be deceiving...
