Elder Dalin H. Oaks of The Quorum of The Twelve Apostles of The Church of Jesus Christ of Latter-day Saints gave up a successful career as a justice of the Supreme Court of Utah (and was considered many times by various Republican administrations for a seat at the United States Supreme Court) to serve his God without payment as an Apostle. He did so without even a second thought.
He is well respected in both the legal field and among religious scholars. He has held many other prestigious posts through his life and is most certainly qualified for this interview. Click on his name if you want to know more about him.
