Both Jews and Catholics have Sacred Tradition, that is, a belief that what God has revealed is found in written scripture, and in the faith that is handed on. Oral tradition being a part of Tradition, but not its entirety. Liturgy is also a major part of the faith handed on. The Feast of the Passover is one such liturgy. Both Sacred Scripture and Sacred Tradition are inspired of the Holy Spirit.
It is true that not all of sacred scripture was canonized. Therefore, we do not have everything which was considered Sacred Tradition in our Bibles.
That reminds me, can you explain to me why the Catechisms delete the second of the Ten Commandments, and then split the tenth commandment into two separate commandments in order to keep the same number of ten commandments?
Okay, back to responding to your comments..... The Hebrews did not write down a great deal of their sacred oral traditions until after Christianity was established. One example is the Kabbalah. Before the Kabbalah was written, few Jews were taught the esoteric doctrines contained in this tradition. Only the learned and those who have gained a spiritual perception of their beliefs are taught from the Kabbalah. Within the Zohar, which is part of the Kabbalah, you can find the following quote:"The souls must re-enter the Absolute, from whence they have emerged. But to accomplish this end they must develop the perfections; the germ of which is planted in them. And if they have not developed these traits in this one life, then they must commence another, a third, and so forth. They must go on like this until they acquire the condition that allows them to associate again with God."
As you can see, the Jews had secret teachings which were not taught to everyone. Also, the above quote indicates that this portion of the secret knowledge was a belief in reincarnation. There are sections in the NT which allude to the Apostles and the Pharisees having this same knowledge, which Jesus never corrected anyone on. Yet the RCC does not believe in reincarnation; in fact, you cannot find a section for reincarnation in the Catholic Encyclopedia which explains why the RCC does not believe in it. When books and epistles were being considered for canonization, the Bishops carefully withheld anything written which indicated that reincarnation was actually something many of the Early Church Fathers believed in.
It is not unusual for us to find in the NT that Jesus taught knowledge to the Apostles which they were not allowed to teach to all members of the church. Paul specifically taught the church in Corinth that they were not yet ready to be taught "meat". I think he could have been referring to the secret knowledge which the Apostles had been taught. Indeed, Jesus told the Apostles that He had not revealed everything He knew to them; but only that which His Father had told Him to reveal. It would be the Holy Ghost who would reveal Truth to individuals once Father deemed that the individual was ready for more Truth. So, neither the OT or the NT reveal all Truth.
I believe Jesus when He said, "unless you eat the flesh of the Son of Man, and drink his blood, you have no life in you".
Yet, Jesus was not actually cutting off pieces of His flesh, nor draining His blood for man to eat and drink - even though He was with them when He taught them about the Sacrament. In fact, we know that the Paschal Lamb was symbolic of the Christ who was to come. The Hebrews had always been taught, since they received the Law from Moses, that they were NEVER to drink the blood. Why would God change and decide that it would be necessary for mankind to drink blood once Jesus had finally come in the flesh, been crucified, and Resurrected? It is SYMBOLIC!!!
He was not being symbolic. Catholic teaching, east and west, is Jesus is Present, body, blood, soul and divinity. This is not a symbol. Just as if I ask you if you drive a car, and you tell me all about the car you drive, you aren't telling me about a symbol of your car. You are telling me about your car.
I beg to differ with you here, as well. One of the core issues of the Great Schism of 1054 AD between the Eastern Orthodox churches and the church of Rome was over this very concept. The Leader of the Eastern Orthodox churches even excommunicated the Pope in Rome; and the Pope excommunicated the Leader of the Eastern Orthodox churches. Today this issue still divides them.
The idea that the bread and wine actually become the flesh and blood of Christ was NOT a sacred tradition. It "became" sacred tradition when the Pope decided to call it such - which, as you can see, was long after Jesus and the Apostles walked the earth.
Therefore, without the personal witness and confirmation of Truth from the Holy Ghost, I am not quick to believe that sacred written or oral tradition which is taught to us automatically means that the tradition is correct, or that we understand those traditions correctly. The Jews in Jesus' day, knew their written traditions. I do not doubt that the Pharisees, scribes, and the Sadducees knew their oral traditions. Yet they crucified our Savior. Their knowledge of both written and oral traditions failed them in much the same way as I see that written and oral traditions have failed you.
The Real Presence of Jesus is also found in His Word...the four Gospels, and in His Church, which He established and has never failed.
Inasmuch as I do believe that the Gospels are sacred to the believer, I place my dependence for being guided to the Truth held within them to the Holy Ghost. He is the witness on the physical earth of all spiritual Truth. God does not "exist" in a book; He is a living God, Jesus is our living Savior, and the Holy Ghost is living to witness and confirm Truth to us today....here and now.
