Interesting scripture. I can think of what does it mean to be a minister of reconciliation, and I see nothing wrong with righteousness. No way should anyone be pretending.
You had to have once been under the old covenant to be put back under it if it is even possible for this to occur, unless you simply mean a person who has never been under the old covenant should not be put under that which is old.
Jesus did not change the law. There has, however, been a change of the law with the change of the priesthood. The question is what this means. A change within the priesthood or a change to a different priesthood? Is it an order of the priesthood, the Levitical Priesthood? What do you know about the Levitical Priesthood if anything? There has been an annulling of the former commandment too, but I do not yet know what this means. It is not that I am blind. Yeshua, Jesus, holds His priesthood permanently. He is of the tribe of Judah, not Levi. He is a priest forever according to the order of Melchizedek. The priesthood of Jesus. He is our High Priest.
I said
Your a minister of satan.
[2Co 11:14-15
14 And no wonder! For Satan himself transforms himself into an angel of light.
15 Therefore [it is] no great thing if his ministers also transform themselves into ministers of righteousness, whose end will be according to their works.
