I actually think Catholics do..
"The priest is, indeed, another Christ, or in some way, he is himself a continuation of Christ." (Pope Pius XI, Encylical on the Priesthood)
The Pope is called " the Vicar of Christ?" Or the stand in for Christ.In calling the Pope the "Vicar of Christ," this implies that he has the same power and authority that Christ had over the Church.
From the catechism
"For the Roman Pontiff, by reason of his office as Vicar of Christ, and as pastor of the entire Church has full, supreme, and universal power over the whole Church, a power which he can always exercise unhindered." Pg. 234, #882
"The Roman Pontiff... as supreme pastor and teacher of all the faithful..." Pg. 235, #891
Do you believe that the Pope speaks for Christ?
You're actually wrong.
Do you believe that the Pope speaks for Christ?
Yes. That's the point. Catholics follow Christ, the leader of the Catholic Church.
His Holiness Pope Benedict XVI is merely His vicar.
