The real question is, why would Jesus create an institution, and then not give it the mechanism to stay on course?
So, Christ instituted a Church. Christ also gathered disciples, many of which he sent out to evangelize, two by two. Christ taught them well, don’t you think? Do you think they weren’t human? Do you think they couldn’t get something wrong, and spread the wrong thing? On their own, of course they could. But Christ not only taught them well, he sent them out with the gift of the Holy Spirit, and they were able to proclaim the Good News. Inerrantly. Does this mean they knew what the weather was going to be, that they didn’t have human emotions, that they were more or less than human? In the words of St. Paul, Of course not! Christ gave his disciples, those he appointed by laying hands on them, the Holy Spirit to keep them from straying off course. He also promised them this gift going forward, to be given to those who followed them. Christ knew the apostles wouldn’t live forever-by human nature, because of the Fall, and because other humans didn’t want that message being sent out. He gave the gift to the office, so that, when the man, the apostle or bishop, exercised his office, he would have the gift. When he was operating in another way, or position, say as a person with his family or friends, the authority of the office wouldn’t be present.
I know, my Reformationist friends think that our doctrines are wrong. They disagree with many of them. But if they would agree that Christ was never wrong, that he gave this charism to his apostles, when they imparted the faith, and that this gift was meant to pass on to their successors, I don’t know how they can say the Church is wrong, and that they are correct. They weren’t expressly given the gift of laying on of hands. I wrote a post a long while back theorizing about when St. Paul actually became an apostle, because I believe (though it’s not necessarily taught by the Church) that it requires that hands be laid by someone who’s had hands laid on them. I think St. Paul had hands laid on him by Peter in Jerusalem. Not that it really matters, it’s a small thing. But the laying on of hands imparts the gifts of the spirit to those being ordained.
