Here is my comment to a discussion about what Judaism is.
The "ancient Judaism" was only a child. The child has grown up.
Rashbi, Moshe d'León, Arizal, Ramchal, Vilna Gaon, Moshiach, all are stages of a cosmic growing-up process, of Moshe Rabbeinu growing up, of Klal Yisrael growing up.
The difference with Yeshu and Mohammed is that they are the end. Only in Judaism there is growth.
