I would like you to notice something here. Those of you who know the world of Peanuts, know that one thing Linus never does is let go of his security blanket. Yet, he does so here, while reciting Luke’s Gospel.
Charles Shultz was no fool. It is a fairly subtle thing, but i believe there is a message being sent here. Of all the things in his life, that Gospel is the one thing Linus is sure enough of that he doesn’t need his security blanket.
