Jesus, the law and the New Testament.

I know the title is pretty broad. But I have a lot of questions and I desire, respectful communication. Any claims that Paul is in apostate is something I will not currently accept. Only the entirety of the new and Old Testament as it currently is. I only have questions and to voice some concerns, but I will not argue with anyone. So please don’t attempt to argue or insult me. That will definitely turn me off and I will walk away. Anyways, let me ask some questions.

Is Jesus your high priest currently?

Is Jesus your sacrifice for sin?

is it possible to observe all the Old Testament law and feast days and requirements? How do you do that exactly?

Is obedience to this law, a requirement for salvation, according to your understanding?

I think just those questions can cover a lot of ground and probably have a lot of verses to support it so let’s just start there and I’ll post on another day when I’m feeling a little bit better.
