It has been a while since I delved into this subject. I use to know reasons why Christ had to be God in order to save his people but my poor mind just isn't as quick as it use to be. One of my friends has been introduced to an old group called the Way International. I am quite familiar with the cult and I can deal with the issues of Christ's deity by scripture. I use to know another argument based upon ontological being but I am having trouble remembering it. So can you all give me some help here? Why did Messiah need to be Ontologically God to be qualified to redeem mankind from sin?
