I am not impure during menstuation and will not wash a sheet I touch less than 7 days after. I will not sacrifice animals. I will not allow my husband to have other wives and concubines. I go by NT strictly, with the exception of the ten commandments.
I agree with you, except the ten commandments. They are frequently referred to as the tables of the (old) covenant, which has been replaced with a new covenant, and new commandments.
Jesus didn't come to destroy the law, but to fulfill and set us free from the law.
Hebrews 8:13 - "In that He says, “A new covenant,” He has made the first obsolete." In like maneer, He made the old commandments obsolete by giving us a New Commandment in John 13:34.
