The trick is that God has to have SOMEONE in mind for the next Traditional bishop.
The other thing is: there is still a grave need for a Bishop. The Resistance only has 3, and there is still not a bishop for North/South America. The new bishop +Dom Thomas Aquinas will be full-time busy doing confirmations circuits in Brazil, and tending to his monastery. Maybe he can go to some countries in South America. But that still leaves the US, Mexico and Canada -- and Asia -- without a bishop.
God isn't going to create a full-grown man for us, much less a man already consecrated Bishop. God makes use of the means He already created (human reproduction to form the man, the Rite of Consecration to create the bishop) to form new bishops.
The next Bishop has to be a priest already, or he wouldn't be old/experienced enough for the task. I suppose he could still be in the SSPX or elsewhere, but wouldn't that be evidence of at least a slight deficiency in prudence, fortitude, trust in God, proper understanding of obedience, or some other virtue a bishop should have?
I think it's most likely the next Bishop is already a priest, and already actively helping the Resistance.
There aren't exactly hundreds of candidates.
I just love to rejoice when I see the side of God win a few battles (for a change!) And consecrating a worthy candidate Bishop -- that's what I call a battle won!
I pray and look forward to the next Consecration ceremony in the Resistance.
