David Peterson is a terrific New Testament scholar. I have benefited much from his work. Dr. Peterson recently wrote three essays on the homosexuality as understood through the grid of of the Bible's teaching on holiness.
1. Holiness and God’s Creation Purpose
2. Holiness and Sexuality in the Pauline Writings
3. Same-sex Unions and Romans 3
Take time to read these helpful essays.
