Teachings from the Church's Magisterium

Jesus and the Twelve are on the lake, in two boats. They come across another Roman boat, with Mary Magdalene on board. Jesus is absorbed in his thoughts while Judas, Peter and Simon the Zealot intervene, mainly because of the Iscariot. Then the Lord asks Simon of Jonah to lead them into a separate corner. He teaches them at length about the essential lines of his doctrine.
