Ellen White does not use the exact phrase "cherished opinions can become idols," but she does teach that anything we love, trust, or cling to in place of God—including our own ideas or opinions—can become an idol. For example, she writes: "Anything that men love and trust in instead of loving the Lord and trusting wholly in Him becomes an idol and is thus registered in the books of heaven. Even blessings are often turned into a curse. The sympathies of the human heart, strengthened by exercise, are sometimes perverted until they become a snare." (Testimonies for the Church, vol. 5, p. 250.1) She also warns against cherishing idols in our lives, which can include selfish pleasures, pride, or anything that takes the place of God: "By many, idols are cherished and worshiped. Put away your idols. Give up your selfish pleasures." (Testimonies for the Church, vol. 6, p. 450.3) While she does not specifically mention "cherished opinions," her principle is clear: anything—including our own thoughts, preferences, or opinions—that we place above God or His truth can become an idol.
