Regarding the person who created the thread, his overall attitude has been one of accusation of spiritual inferiority. Read his threads.
By the way, he got most of his materials from 119ministries.com and did not even acknowledge his source. He was simply spoon feeding their heresies to others here.
Relating to God's moral law, it is forever. Ceremonial or ritualistic laws are not. The Sabbath, Holy Days, clean and unclean meats, triple tithing, and physical circumcision would definitely fit into that category.
One can see the relationship by the language used in Scripture concerning them. Notice that the language of shadows is used for both animal sacrifices and the Sabbath/Holy Days:
Heb 10:1-2 For since the law has b
ut a shadow of the good things to come instead of the true form of these realities, it can never, by the same sacrifices that are continually offered each year, make perfect those who draw near. Otherwise, would they not have ceased to be offered, since the worshipers, having once been cleansed, would no longer have any consciousness of sins?
Col 2:16-17 Therefore, let no one pass judgment on you in question of food and drink, or with regard to a festival or new moon or Sabbath. These are a s
hadow of things to come, but the substance belongs to Christ.
Jesus Christ observed all of the Mosaic Covenant. He was a Jew born under the Old Covenant, and part of his mission was to fulfill it perfectly.
Jewish Christians continued to observe elements of the Old Covenant even after the crucifixion. However, they were not obligated to do so. It was part of their culture.
Gentile Christians were never obligated to do any of the ceremonial and ritualistic elements of the Old Covenant. Acts 15 addresses this.
The person who created this thread was using heretical sources including Restored Church of God as well as 119ministries.com. Restored Church of God is an Armstrongite cult that claims to be the true church and teaches that their followers are to become literal God beings in the resurrection. It's not very hard to detect that such a person holds unorthodox doctrine.
I agree that if a person wants to keep the Sabbath and Holy Days without claiming that they are a requirement or condition or necessary fruit of salvation, they shouldn't be judged. There are individuals like that on this site. This person was not one of them.
By the way, he practices deceit and lying by setting up new usernames using untrue information on them, including changing his age and marital status. While accusing other Christians of being disobedient due to not keeping the Sabbath, Holy Days, physical circumcision, etcetera, he violates a moral absolute such as lying. How much credibility do we give to his claims based on that?
Col 2:16-17
I suppose the orthodox explanation here would be: "The law is forever, but this only applied to the Israelites, or people who were under the Israelites' covenant."
I here this explanation often in my church. But I have two problems with it:
1) God said that the same laws apply to both the jews and the foreigners living among them. So it couldn't just be for the isrealites.
"'A foreigner residing among you is also to celebrate the LORD's Passover in accordance with its rules and regulations. You must have the same regulations for both the foreigner and the native-born.'"---Numbers 9:14
2) There's no scripture that suggests that God's law isn't part of the new covenant. In fact, the prophecy in Jeremiah regarding the new covenant puts it like this:
"This is the covenant I will make with the people of Israel after that time," declares the LORD. "I will put my law in their minds and write it on their hearts. I will be their God, and they will be my people.-----Jeremiah 31:33
Now I wouldn't go so far as to say that torah observance is a requirement of salvation. But it worries me when people are hostile to what it says, and go so far as to vehemently attack those who do follow it. Calling people a "judaizer" or a "heretic" for reading the torah is illogical, because the messiah himself kept those commandments, and he was our example. By that logic Jesus was a judaizer too, since said that his people had to do everything the Pharisees taught during the sermon the mount.
There's no reason to dismiss the torah as a part of Christianity, and there's no reason to push it on others. We should all just agree to respect eachother regardless of what commandments we choose to follow, and leave the judging to God.
