As for fulfilling the law, I don't think it ceased. Obviously, you did not comprehend what I wrote. Let me try and explain it to you.
Overall, I think you're a good discerner of Scripture, but I do disagree with you on some points. I won't waste my time with BrotherD. He shows he is not interested in dialogue but I see you as a brother in Christ so I wanted to give you my understanding to see if you find it reasonable.
Regarding the OT law, if it has not ceased then where are the annual animal sacrifices of atonement, the priesthood, the temple, the OT economy, the feast days, the genealogies? Not only this, Christ has fulfilled the law for the believer, whether Jew or Gentile. I know you believe that. The Law of Moses has been abolished (Matthew 5:17-18) since it can no longer be carried out in the prescribed manner. It was always pointing to the better covenant, a schoolmaster or tutor to lead us to Christ.
Galatians 3:23-25 (NASB)
23 But before faith came, we were kept in custody under the law, being shut up to the faith which was later to be revealed. 24 Therefore the Law has become our tutor to lead us to Christ, so that we may be justified by faith. 25 But now that faith has come, we are no longer under a tutor.
Matthew 5:17-18 (NASB)
17 “Do not think that I came to abolish the Law or the Prophets; I did not come to abolish but to fulfill. 18 For truly I say to you, until heaven and earth pass away, not the smallest letter or stroke shall pass from the Law until all is accomplished.
Do we see every letter of the law still being practiced today?
Romans 7:6 (NASB)
But now we have been released from the Law, having died to that by which we were bound, so that we serve in newness of the Spirit and not in oldness of the letter.
His sacrifice and resurrection have accomplished what the Law could not for those who have faith in Him.
What did Jesus mean when He said: "until heaven and earth pass away"?
The unbeliever still shows he has the law written on his heart.
Romans 2:14
14 For when Gentiles who do not have the Law do instinctively the things of the Law, these, not having the Law, are a law to themselves, 15 in that they show the work of the Law written in their hearts, their conscience bearing witness and their thoughts alternately accusing or else defending them, 16 on the day when, according to my gospel, God will judge the secrets of men through Christ Jesus.
The OT law is still ongoing in the NT. The difference is the letter not the spirit. Jesus did not stop the law. Yet he fulfilled it. The OT law of sacrifice was at its heart about what?
The OT law is the Law of Moses. Thus, it was still ongoing during NT times until AD 70. Jesus fulfilled the law for those who believe. He nailed the letter of the law, the punishment for breaking it to the cross. It is shown to be complete in that His one sacrifice is all the believer needs. For the New Covenant to be the only one needed the Old Covenant with all its sacrifices had to disappear. The Covenant God made was with specific people - OT Israel. The disappearing and replacement are what Hebrews is all about.
Hebrews 8:13 (NASB)
13 When He said, “A new covenant,” He has made the first obsolete. But whatever is becoming obsolete and growing old is ready to disappear.
Hebrews was written primarily to Jewish believers in Christ who were thinking about returning to Judaism. Hence, the author (many believe it to be the Apostle Paul) could say in Hebrews 9,
8 The Holy Spirit is signifying this, that the way into the holy place has not yet been disclosed while the outer tabernacle is still standing, 9 which is a symbol for the present time. Accordingly both gifts and sacrifices are offered which cannot make the worshiper perfect in conscience, 10 since they relate only to food and drink and various washings, regulations for the body imposed until a time of reformation.
Still standing. That would signify before AD 70 when the temple and city were destroyed by the Romans.
16 For where a covenant is, there must of necessity be the death of the one who made it. 17 For a covenant is valid only when men are dead, for it is never in force while the one who made it lives. 18 Therefore even the first covenant was not inaugurated without blood.
Christ's blood, His life, His sacrifice of atonement, has initiated the New covenant. The two covenants were in transition for 40 years from His death until the judgment was fulfilled in AD 70 for the sins of those who did not believe in Him (see Hebrews 3).
25 nor was it that He would offer Himself often, as the high priest enters the holy place year by year with blood that is not his own. 26 Otherwise, He would have needed to suffer often since the foundation of the world; but now once at the consummation of the ages He has been manifested to put away sin by the sacrifice of Himself. 27 And inasmuch as it is appointed for men to die once and after this comes judgment, 28 so Christ also, having been offered once to bear the sins of many, will appear a second time for salvation without reference to sin, to those who eagerly await Him.
He appeared in AD 70 the second time as He told His disciples He would while some of them were still alive.
Matthew 16:27-28 (NASB)
27 For the Son of Man is going to come in the glory of His Father with His angels, and will then repay every man according to his deeds.
28 “Truly I say to you, there are some of those who are standing here who will not taste death until they see the Son of Man coming in His kingdom.”
If you get the wrong audience of address AND/or wrong timeline or time statements, you risk misinterpreting Scripture. Who is the audience of address, the 'you' spoken of here? What is the timeframe in reference to - the OT economy, which still is functioning at the time of the writing of Hebrews.
It was about atoning for the sins of people in a temporary way because the blood of goats and cows are not eternal. Jesus however as the Eternal Son of God has blood that atones eternally - for the sins of his people. Hence, the OT Mosaic system is known as a shadow of things to come - namely Jesus who is the real deal. therefore, the atoning sacrifices has not ended or been ceased in spirit - but in Christ is eternal for all his people.
Hence, not ceased, but fulfilled in Christ. I notice you OMITTED to explain what fulfilled was according to your own thinking. Perhaps it is you who is running away from the obvious. Yes, you said what you think it was not. but OMITTED to say what you think it was.
Abolished would mean ceased (Matthew 5:17-18). If Christ has obtained eternal redemption then what need is there of the Law of Moses for the believer. The unbeliever still shows he/she understands the law of God for he/she still knows it is wrong to lie, murder, steal, commit adultery, covet, etc. Thus, he/she shows he/she is still answerable to God in breaking His laws. Thus, the believer and unbeliever are living under the grace of God. He allows the sun to shine on both for a period of time (Acts 17:24- to the end of the chapter). The unbeliever still thinks their good works are sufficient to save them. They still think their deeds are good enough to meet God's perfect standard. Thus, they ignore or see no need for a Savior. They think they can accomplish only what God could by His grace, His Spirit, His Son.
