I'm afraid you have been mis-informed and misled.shalom b'SHEM Yah'shua HaMashiachMay you seek the YHvH of the Holy Word of G-d.
Seek His face in His Holy Word.
Then one day, you will be grafted into His Chosen People.
See Romans 11 as to who is grafted into whom.
You seem to think, or imply, that I take what others say at face value. I do not. When I left Mormonism, I spent YEARS studying Greek and Hebrew and the Scriptures. I don't take anyones word for anything. My theology is my own and it is biblical. My degrees and my studies have taught me well and I don't even trust my pastor without researching it and going back to the texts. You apparently are the one that is misinformed. I am grafted into the Body of Christ and gratefully so. You keep mentioning Romans 11 but apparently you neglect the rest of Romans and the New Testament. May God open your eyes has he has mine.
