Nathan has also been a major force for immigration reform, highlighting the issue in both sermons and op-eds. He advocates for a different plan than those traditionally offered for America's illegal immigrants, "a pathway to citizenship governed by a system of checks and balances." He has led Vineyard Columbus to embrace racial and ethnic diversity.
Vineyard Columbus is one of America's most diverse churches, having attendees from over 125 nations. Nathan has been a leader in the Vineyard movement in advocating for women's full participation in all aspects of church ministry including becoming senior pastors, church planters, missionaries and Vineyard Association overseers. As Nathan put it in a message on egalitarianism:  "God's gifts and call are not gender-based."
