Wonderment - I agree, with much of what you say.
I feel differently on a few points. You said "Many of the Judaic laws do not apply now" I agree, however this is not because Christ replaced them with something else, Rather, he erased them because they Never Applied in the first place, and they were never Commanded by God. No one ever had to Sacrifice Animals, this was a man made tradition, which was corrupt in many ways.
Jeremiah 7:22 "For in the day that I brought them out of the land of Egypt, I did not speak to your fathers or command them concerning burnt offerings and sacrifices."
Psalm 40:6 "Sacrifice and offering you did not desire-- but my ears you have opened -- burnt offerings and sin offerings you did not require."
Hosea 6:6 "For I desire mercy, not sacrifice, and acknowledgment of God rather than burnt offerings."
The Temple arrangment was not required or necessary either..
Isaiah 66:1 "This is what the LORD says: "Heaven is my throne, and the earth is my footstool. Where is the house you will build for me? Where will my resting place be?"
John 4:20 "Our ancestors worshiped on this mountain, but you Jews claim that the place where we must worship is in Jerusalem."
Jeremiah 7:4 "Do not trust in these deceptive words: ‘This is the temple of the LORD, the temple of the LORD, the temple of the LORD."
You said that Principles of the Old system carry over to the New.. I agree, please give me your opinion on one of these principles.
God requires that we be kind and compassionate to animals. - "And the angel of the LORD said to him, “Why have you struck your donkey these three times? Behold, I have come out to oppose you because your way is perverse before me." Num 22:32
"Whoever is righteous has regard for the life of his beast, but the mercy of the wicked is cruel." Proverbs 12:10
If you were to come upon a Man torturing a Cow, only to Slaughter it ruthlessly and without care for its suffering, would you proceed to Reward that Man, and Buy the Meat of the Cow and eat it? Would you continue to pay for that beef, knowing that more Animals Undergo unmentionable pain and suffering, for the satisfaction of your belly?
If you do not follow the Dietary Laws of the Mosaic Law, this is Exactly what you are doing.
