A very human Rock, saint Peter (Cephas, the rock) was not declared to be sinless by Jesus, nor was he promised unerring goodness in all his works and actions. After all, he did deny Jesus three times, as Jesus said he would, nevertheless the risen Lord, Jesus, restored him to office asking, "do you love me more than these" and twice more "do you love me" and each time receiving from Peter an affirmation of Peter's love to which Jesus said, "feed my lambs" and "feed my sheep" and again "feed my sheep". So, a man who sins like others is made by the Lord, Jesus Christ, a pastor to feed the sheep that are Christ's people, his special flock, the flock of God.
