I am sorry but that is exampling more ignorance. God did not change His mind, but foretold "Behold, the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah: Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the Lord: " (Jeremiah 31:31-32)
And in Scripture there are different covenants and a manifest distinction between purely moral laws, which are transcendentally directly applicable to all cultures (no idolatry, adultery, etc.), as well as culturally applied laws (fence around your roof) which are based on them and are applicable to different cultures by adaptation based on principal, and then there are typological/ceremonial laws, which relate to ritual observance of "days, and months, and times, and years. " (Galatians 4:10) and "in meats and drinks, and divers washings, and carnal ordinances, imposed on them until the time of reformation," (Hebrews 9:10) "Which are a shadow of things to come; but the body is of Christ." (Colossians 2:17)
The requirement of a sacrificial lamb for instance was a type foreshadowing of Christ who made the shadow, and laws against unclean foods typified the Gentile who are made clean by Christ. While the holy intent of all the laws are to be fulfilled by Christians, and which requires the literal keeping of moral laws beyond just the letter, the literal observance of ceremonial laws are not, but such things as the principal of separation from defilement is, and looking to Christ as the Lamb of God which taketh away the sins of the world. (Jn. 1:29)
While relativists seek to dispense with transcendent moral laws based on the abrogation of ceremonial laws, this is contrary to "Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth. " (2 Timothy 2:15)
The polite thing to do, once the moderator has told someone they are not to be on this thread, is to stop pinging them.
