A common misinterpretation views this verse as entirely rejecting animal sacrifices or ritual worship altogether, suggesting God despises all such practices regardless of intent, whereas the passage specifically critiques insincere, heartless religion among those delighting in sin; another error applies it to invalidate Christian sacraments like communion or baptism as futile rituals, ignoring the context of Israel's covenant unfaithfulness and the prophetic call for authentic repentance over external piety.
Isaiah 66:3
King James Version (1769)
3 He that killeth an ox is as if he slew a man; he that sacrificeth a lamb, as if he cut off a dog’s neck; he that offereth an oblation, as if he offered swine’s blood; he that burneth incense, as if he blessed an idol. Yea, they have chosen their own ways, and their soul delighteth in their abominations.
Isaiah 66:3 condemns hypocritical worship where outward religious rituals like sacrificing an ox or lamb, offering oblations, or burning incense are performed without a heart aligned with God, equating such empty acts to heinous sins like murder, offering dog's blood, swine's blood, or idolatry because the people have chosen their own rebellious ways and delight in abominations, emphasizing that true worship requires sincere obedience and devotion rather than mere formalism.
