Pistis Christou can be either an objective genitive (Faith in Christ) or a subjective genitive (Faith of Christ).
I presume the decision is theological. I don't have a position on this, but I know it's debated among theologians. I remember being taught with great force, anger, and frustration by my TWI teacher that faith is something we have and believing is something we do, but I don't remember how pistis Christou was handled. And then there's believing faith. MOREOVER, believing is part of the equation that defines the word of God. It seemed like pistis could mean whatever whenever, according to the size of the glove and the amount of snow.
Though there are other verses, these two seem especially important: Galatians 2:15-16 and Romans 3:21-26.
Three questions:
How do you handle the objective/subjective genitive?
Asset or Liability?
Lo Shonta?
