Absolutely, 100% NOT!
I'm a klutz, a doofus, a schlemazzle -- all that and more! (or less!) (And one of my favorite sergeants had a picture of Barney Fife above his desk -- but I'm not sure that counts.)
We keep saying this and it feels like nobody is listening. Jesus is great. You can count on that. You cannot count on the Pope being great. You can count on Jesus' promise to the Church.
They say, as I never tire of saying, that Mount Sinai is a pretty scuzzy mountain. You don't come away from it saying,"Wow, what a mountain!" You come away from it saying, "Wow, what a revelation, what a wonderful Torah, what a great God!"
Yeah, you get a guy like JPII and he's pretty impressive. But even he will tell you that the POINT is to say not,"Wow! That is some pope!" but "Wow, that is some Lord!"
I am reminded of Moses who didn't have confidence in his speech, David who was tiny compared to Goliath, Abraham who passed his wife off as his sister - and so on.
Of all of them, Paul was the least likely (from a human's viewpoint) to become an apostle having persecuted the believers relentlessly.
And yet God used them all - and He uses every one of us, too.
p.s. This is another case of the observer problem. We mortals look at the back of a wristwatch and see everything working against itself. God looks at the front, where it is keeping perfect time.
