João 21
Alcuin of York
João 21:15
[(as quoted by Aquinas, AD 1274)] 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. — Catena Aurea by Aquinas
João 21:17
[(as quoted by Aquinas, AD 1274)] 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. — Catena Aurea by Aquinas
