I stand alone on the Word of God. As Martin Luther said to his accusers (in paraphrase), show me where I’m wrong from the Word of God and I will surely repent of my errant views.
Would you agree that a possibility exists that two honest Bible scholars may come to different conclusions about this issue?
Absolutely. One may be right and the other wrong, or they may both be wrong, but they cannot both be right. No man is perfect in his interpretation of the Word of God. All men can and do make mistakes, including me. Some eminent Bible scholars have changed long held views of the Bible.
Have you a revelation from God supporting your conclusion and invalidating theirs?
Nope. I stand alone on the Word of God, which I am ready to discuss at any time. I am ready to compare any interpretation of Scripture with my understanding. If I can be shown to be wrong, I am prepared to change my interpretation to be more faithful to the Word of God. In fact, I have changed my opinion many times. In my younger days, just after my conversion, I used to believe many of the thing commonly believed about Israel, etc. I have since discarded most of those ideas because I found they were not entirely true to the Bible.
Do these two different interpretations of Scripture effect the historic creeds of the church?
Not sure what you are asking. I do not believe that certain modern views wrt the Church and Israel are biblical and fit with the historic views of the Church, esp. the Reformed Church that I’m a member of.
You said before, I don't believe that the new covenant eradicates the old. I asked you in what way then is the old covenant still in effect? And your biblical basis for such a conclusion.
