I know that this will not be an answer that will find much agreement but here goes anyway.
The pope is only in charge of an organization, the Catholic church.
Christ is in control of HIS church and would certainly not put it in the hands of sinful man. The pope is in charge of the Catholic church, not Christ’s church. If the pope were the leader of Christ’s church then he would not have let all the abuses that have gone on it the Catholic church over the years go on.
well, perhaps you should re-read the Gospels; Christ chose the one who betrayed Him to found His Church upon.
To say that Christ would not put His Church in the hands of sinful man is to say that he would not put it in charge of anyone, as we are all sinful. How then, is a decision to be made, if not other than by sinful men? If there is error, who is to correct it, other than sinful man?
and if there is truth, if Christ gave us truth, then why are the 20,000+ denominations squabbling over what that truth is, except for the fact that they refuse any leadership inspired by the Holy Spirit?
And since many of them, if not most, claim that the Holy Spirit is leading them, and yet they persist in major disagreements as to what that truth is, it will do you little good to claim that the Holy Spirit is going to take care of it all; even a casual look around might convince one that the holy Spirit has taken a several centuries holiday.
