Tradition and Torah intermixed

The Mishnah tells us all about the four cups (Pesachim 99b). But how much farther back does the tradition go? We know that Yeshua’s seder meal used the red wine to refer to His blood (Luke 22:20 - Christians know this as the "eucharist"). We also know that the same was used centuries before the time of Yeshua (for example, see the Book of Jubilees and Philo). Yet, we also know it is not in the Torah. What does this tell us? Some may draw from this that authority be given to the notion of Torah Shebe Al Peh (Oral Torah). But for those of us who have come to know the Messiah, the Living Word, it shows that we have freedom to incorporate our traditions, even as Yeshua did. For us, Messiah the Passover Lamb is the center and illumination, not only of the Scriptures, but also of Jewish history.
