Let me offer this: On the 500 anniversary of Luther tacking his 99 Thesis on the doors of Wurtinberg Cathedal (please forgive my factual errors, I am writing from memory), the Roman Catholic Church and the Lutheran Church of Germany entered into an agreement saying:
1. We are saved by faith alone.
2. Our good works are a sign of our joy for being saved.
3. We are in agreement on what is most important.
I would add to this, being of the Messianic Jewish persuasion, that to inquire too sharply as to the nature of God is to ask the impossible. But, this we can say, God, who in his majesty cannot be fully known to the human mind, manifested himself in the person of his son, Jesus, Yeshua. By this, which is the Good News, we are able to better know him and be assured of his love for us.
