The Court approached the case through the lens created in "Lemon v. Kurtzman". It agreed that if Kentucky's statute broke any of the three guidelines outlined in the Lemon test, the statute would violate the Establishment Clause. The majority held that The Commandments convey a religious undertone, because they concern "the religious duties of believers: worshipping the Lord God alone, avoiding idolatry, not using the Lord's name in vain, and observing the Sabbath Day." But since "the Commandments are integrated into the school curriculum, where the Bible may constitutionally be used in an appropriate study of history," they have no secular purpose and a definite religious purpose.
