David is the only one man in the entire Bible called “a man after God’s own heart” (cf. Acts 13:22; 1 Sam 13:13-14). Anointed by God, he established the Golden Age for the kingdom of Israel. From the time of Samuel the prophet onward, David became the prototype of the Messiah yet to come.
No Pope will ever win the universal applause of the world. The Pope proclaims divine revelation. The world wants only human opinion. The Pope is bound by the Word of God. Along with the college of bishops, indeed with the whole Church, he listens attentively to the Word, and, then, by the charism of his office, he offers the saving truth of our redemption.
