I was not clear, that is exactly why they did not like MacArthur. As I remember it MacArther preached it was the substitutional death of Jesus that paid for our sin and he minimized the importance of the shed blood. As I recall he taught that the method was not significant, outside of fulfilling prophecy, but the necessity was his death.Which is interesting to me since I remember more than a couple IFB preachers decrying denominations that eliminate the blood from their proclamation of the Gospel.
Many within the IFB camp felt he was taking the significance from the blood of Christ which they believe to be essential (Hebrews 9, 1 John 1. 1 Peter 1).
