Abraham believed in G-d without being a witness to the events at Sinai several hundred years later but the implication is that because Abraham believed in G-d without the full extent of the law then so can all of humanity for faith is better then fulfilling rules for their own sake, or so the Gospel says. Again we Jews would disagree because Abraham had faith because he understood that G-d is law and hence that the Torah would be considered G-d's supreme law.
"God is Law"? Where does it say that- without interpretations cast upon any text- in the Torah? I know what you are saying, but the law is given to men...so while God is the source of law and a reflection of His character He is more than that.
The NT is the continuation of God's process of revelation (self-disclosure) that began in Eden. In the NT, we are told that God is Love. (Not "love is God") Our understanding is kind of deep on that- too deep for this forum, but we all know that He has other attributes.
Your comments are ok as far as human philosophy goes, but really, they cast interpretations upon texts rather than read them as they are. By emphasizing the "law" of God one de-emphasizes His mercy.
The Jewish people as a whole act in the position of the priest and the world would be the people of the priest. So in essence the law of Moses is still in effect, as I believe most "Messianic Jews" would agree to a certin extent, and hence we Jews have an obligation to fulfill it until the end of time.
No one can fulfill the Torah- this is called being realistic. Saying that Jews are obligated to fulfill it doesn't make sense on that basis alone. If we are obligated to fulfill every part of it- then start stoning people, killing animals and so forth....the facts stand in the way of the ideal. The Rabbis have invented- since Messiah has come- a religion that reads well, but it simply falls short of the Torah. It is not the Torah religion- it is a religion that has nostalgic connections to the Torah. The Messiah's religion is harder to live by, yet it is available to all. God Himself as Lord of history has made the whole Torah impossible to fulfill.
Anyway- the discussion could ask : How is the law "fulfilled"? This is important. Is it fulfilled by merely keeping it properly (impossible for any human) or is it fulfilled when not just faithfully kept but also brought to its full meaning (as the NT teaches)?
Of course Jesus Christ brings up the trinity and so the concept of grace fulfilled in Christ's death is seen as him becoming the "king of kings" and so when Paul is speaking in "The Letter to the Galatians" he is telling them to see the Torah as a bridge in the coming of Christ and that because Christ has come the world is no longer subject to "the law" and are now under the law of salvation in Jesus. Or at least that is how I am reading the text.
I don't really know what you are saying, but you need to remember that Paul is addressing a congregation- largely Gentile- that was being told they had to be circumcised to follow Jesus. This is not the Gospel, nor is it in the Torah. Paul is simply defending both. Read Galatians in the light of Acts 15 etc.
How can the Torah be considered slavery if G-d presented it to Moses on Mount Sinai and why would G-d not have simply presented the Gospel or have sent Christ 1500 years before He did in order to save humanity?
Two different questions there. First of all, according to the whole NT the law is more like a marriage than slavery- it is a binding. No English translation will be precise on this...but slavery is merely one acceptable translation of the Greek word there. Bondage is ok too. Israel was married to HaShem, and she was not a very good bride. She was adulterous. The laws of the marriage covenant were not kept. God knew this from the start, from eternity. He sent His Son to reconsile us to Himself. His Son a holy man offered to God, and also God offered to man. That makes Him both High Priest and sacrifice.
Killing an animal was merely a symbol to show us about the offence of sin and its just punishment. God Himself alone can take sins away, and this new covenant by the blood of the Cross is honoured and sealed with blood by God Himself. This is just as the covenant with Abraham was. Abraham and his seed could never honour the covenant perfectly so God made it Himself (Gen 15).
This is a mystery, prophecied in the Tanakh (as seen in ancient texts) but revealed in its fullness on earth at God's appointed time. God has likewise joined the church to His Son, and ingrafted this church spiritually into faithful Israel. Therefore the Bride of Messiah has always been Israel and now also Gentiles.
Perhaps God's timing of the Cross is a mystery to us mere humans, but it was the right time according to Him. The whole world has never been the same since and I think even Christianity's harshest critics would agree.
