So when they had dined, Jesus said to Simon Peter,
Simon, son of Jonas, do you love me more than these?
He said unto him, Yea, Lord; you know that I love you. He said unto him,
Feed my lambs.

He is called Simon, son of John, John being his natural father. But mystically, Simon is obedience, John grace, a name well befitting him who was so obedient to God's grace, that he loved our Lord more ardently than any of the others. Such virtue arising from divine gift, not mere human will.
To feed the sheep is to support the believers in Christ from falling from the faith, to provide earthly sustenance for those under us, to preach and exemplify withal our preaching by our lives, to resist adversaries, to correct wanderers.
