Can surgery change people's chromosomes? No. So my previous take is mostly correct. All these cosmetic surgeries are bullshit for about 98.3% of the population. I do concede that there are people with naturally occurring genetic mutations that make their SEX unclear.
I don't think you understand what you are saying. Jesus fulfilled the law by living a perfect sinless life. His teachings still accomplish their original purpose, which was: Don't SIN. Now, which prophet lived a sinless life prior to Jesus? NONE! Christians are not under the Mosaic Law; we are under Christ's Law. Only by faith in Christ can you truly be rid of sin. Mosaic law just some bureaucratic place holder, Christ was the real deal.
" yet we know that a person is not justified[
a] by works of the law but through faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be justified by faith in Christ and not by works of the law, because by works of the law no one will be justified." - Galatians 2:16
