To the One True Church that is supposedly protected by the Holy Spirit?
Then it's not the OTC after all, is it?
That understanding is too simplistic.
One of the most famous comments about the actions of the Spirit in a conclave came from the person who is now the Pope Emeritus. In 1997, when asked on Bavarian television whether or not the Spirit chooses the pope, the then Cardinal Joseph Ratzinger answered:
I would not say so, in the sense that the Holy Spirit picks out the Pope I would say that the Spirit does not exactly take control of the affair, but rather like a good educator, as it were, leaves us much space, much freedom, without entirely abandoning us. Thus the Spirits role should be understood in a much more elastic sense, not that he dictates the candidate for whom one must vote. Probably the only assurance he offers is that the thing cannot be totally ruined.
The renowned German theologian got to the heart of the matter: There are too many contrary instances of popes the Holy Spirit obviously would not have picked!
