It is with deep sadness that I write to you to resign from the Council of Delegates of the Christian Reformed Church. A church resignation letter is a formal written notice announcing the intention to leave a position with a religious organization. This serves as a formal written notice stating the intention to leave the church position. I did leave, and am now in a new place much better for me. Thank you, thank you, for all you've done, for your sweet heart for the Lord and for your neighbors. Your membership in the church is voluntary according to the law. You may end a voluntary relationship at any time.
