Moreover, any good theologian understands the right to self-defense and the principles of just-war theory.
The old testament says that. Who in the old testament decided when the time is right for war?
The old testament also contains a whole list of laws controlling how you're supposed to live your life and punishments that are to be meted out if you don't follow the law, such as being put to death for cursing your father or mother or for committing adultery. (Leviticus 20)
Do you believe we should be following these laws?
Most 'good' theologians are selective about what parts of the Bible they choose to obey and those they choose to ignore. For example, they pick out the part about a time for war when talking about self-defense and ignore what Jesus said to do when their enemy smites them on the cheek.
The new testament supersedes the old testament, does it not? What does Romans 12 say about self-defense and how we're supposed to treat our enemies?
superceding doesn’t mean the OT is now somehow wrong or not relevant in our lives. you want to say the 10 commandments aren’t to be followed or shouldn’t be taught as something to attempt to love by just because we’re under grace?
I have a simple answer. Since I’m a member of Christ’s original church, I understand that Sola Scriptura is a mistaken doctrine. I know where the Bible comes from, and I know where individual interpretation goes to: heresy.
God bless you.
