Reverend William D. Westervelt, a well-known pastor and author in Honolulu, brought a strong spiritual voice to Hawaii’s war relief efforts. Through sermons and public talks, he urged unity across ethnic and religious lines, emphasizing that moral duty included both prayer and active service. He supported Liberty Loan campaigns and encouraged his congregants to contribute to Red Cross drives and volunteer work. Westervelt’s writings and public outreach played an important role in framing the war as a test of national character and spiritual conviction.
