Like i said, i dont know all of his teachings, and certainly wouldn follow the ones you mentioned.
Lets take the first, the ones who wrote bible couldnt have wrote it in any different way, because its supposed to be the same god, so he had to write that Jesus approves. Since i dont believe in god or in any holy intervention writing the book so i would direct this to political reasons, to connect the two gods to the same, the Jewish and the new.
As for second, no comment
Btw, im just speculating, dont have any actual evidence
