Refuting Christians with their Own Bible

[Angrboda]

Because they're often vague and unclear, and don't sufficiently cover everything to do with morals.

I disagree. He summed up the law and the prophets with two commandments: 1) love the Lord your God with all your heart, mind, and soul and 2) your neighbor as yourself. He explained that everyone was your neighbor. Further instruction and detailed examples were given in the other dozens and dozens of chapters. 

The commandments here are to have agape for God and your neighbor, both. Insofar as agape for God does not require treatment as equals, neither does having agape for one's neighbor imply fairness and justice.

Modeling our relationship with our neighbor on our relationship with God leaves many questions of just what this agape is to consist of.
