Cardinal Mahoney has his own blog, in which he wrote about his experience at the conclave. This little tidbit is interesting:
When we eventually arrived at the Sistine Chapel on March 12, I was still pondering two or three candidates. However, when the first blank ballot was given to us, and when it was time to write down a name, something powerful–and strange–happened.
I picked up my pen to write, and I began. However, my hand was being moved by some greater spiritual force. The name on the ballot just happened. I had not yet narrowed my thinking down to one name; but it was done for me.
I wrote it, then trembled deeply. That’s when I knew the Holy Spirit was fully working within the Church of Jesus Christ, and that my role was not to “select” the new Successor to Peter, but to “write down” his name–a name that had been given to me. (Source)
This applies more broadly to every clergyman in every daily situation. Their job is not to make decisions as much as to implement the decisions they have discerned from God (the same would apply to the laity, by the way). That’s why seminary needs to put more emphasis on spiritual growth rather than intellectual knowledge, even though the latter is important too.
