Jesus taught us many things. But so did Muhammad and Buddha and countless others. You don't need priests or prophets to teach you. People and events in your life can teach you.
It is one thing to remember, another to know. To remember is to safeguard something entrusted to the memory. But to know is to make each thing one's own, not depend on the text and always to look back to the teacher. "Zeno said this, Cleanthes said this." Let there be space between you and the book.
