Killing Sacred Cows
Origin of the phrase “sacred cow”
The expression “sacred cow” comes from the reverence shown to cattle in India within the religious worldview of Hinduism. Because cows are regarded as holy and must not be harmed, English speakers began using “sacred cow” metaphorically in the 19th century to describe anything placed beyond criticism, question, or change. The phrase “sacred cow” came to describe something treated as untouchable—beyond question or change. In church life, these are often long-standing traditions, preferences, or habits that feel essential but were never commanded by God.
Jesus Confronts Sacred Cows
The danger is not tradition itself. The danger is when tradition becomes immune to evaluation, even when it no longer serves the mission of Jesus. In Mark 7, Jesus confronts this very issue head-on. Religious leaders question Jesus because His disciples do not follow the tradition of ceremonial handwashing. This practice was not found in the Law of Moses. It was a respected, time-honored religious custom passed down by elders. Jesus’ response is stunning:
“You leave the commandment of God and hold to the tradition of men.” (Mark 7:8)
He then quotes Isaiah:
“This people honors me with their lips, but their heart is far from me; in vain do they worship me, teaching as doctrines the commandments of men.” (Mark 7:6–7)
Jesus exposes the core issue: They had elevated tradition to the level of divine authority. Their sacred cows had become more protected than God’s commands.
How “sacred cows” show up in churches
In churches, sacred cows are rarely labeled as such. They are usually called:
• “Our heritage”
• “Our way of doing things”
• “What has always worked here”
• “What people expect”
• “What makes us who we are”
But practically, a sacred cow in a church is a tradition, preference, or structure that is treated as untouchable—even when it no longer serves the mission of Jesus. Examples often include:
• Service times and formats that no longer fit the community
• Programs that drain energy but produce little disciple-making fruit
• Leadership structures that protect comfort rather than enable mission
• Ministry styles, dress codes, or facility uses that silently communicate “insider culture”
• Decision-making habits that prioritize member comfort over reaching outsiders
The problem is not tradition itself. The problem is when tradition becomes immune to evaluation. At that point, the church subtly shifts from asking:
“Does this help us make disciples?”
to
“How do we protect this from being changed?”
Why sacred cows are dangerous to mission
Jesus consistently challenged sacred cows in His day:
• Sabbath traditions that overshadowed mercy
• Purity customs that kept sinners at a distance
• Religious systems that valued rule-keeping over people
He did not reject God’s law. He rejected man-made additions and cultural habits that blocked people from God.
Sacred cows are dangerous because they:
1. Consume energy that should go toward disciple-making
2. Confuse preference with faithfulness
3. Create insider culture that outsiders feel but cannot name
4. Prevent adaptation to new people and new contexts
5. Shift the church’s emotional center from mission to maintenance
A church can be biblically sound and still be missionally stuck because of sacred cows.
How to identify sacred cows
A simple diagnostic question: “If we stopped doing this tomorrow, who would be most upset—and why?” If the answer is:
• “Because it’s biblical” → not a sacred cow.
• “Because it helps us make disciples” → not a sacred cow.
• “Because it’s what we like / what we’re used to / what we prefer” → likely a sacred cow.
Another question: “Would we start this today if we were planting the church from scratch?” If the honest answer is no, you may be looking at a sacred cow.
How to avoid sacred cows as a church
A mission-centered church adopts a different posture:
1. Hold doctrine tightly, hold methods loosely. The message never changes. Methods must.
2. Evaluate everything by one question. “Does this help us make disciples of Jesus?” If not, it is negotiable.
3. Create a culture where change is normal. When change is rare, every change feels like betrayal. When evaluation is normal, change feels like faithfulness.
4. Teach people the difference between biblical conviction and personal preference. Many sacred cows survive because people confuse the two.
5. Regularly “reset” like a church plant. Ask: If we were starting fresh to reach our community, what would we do?
A church that refuses sacred cows
Such a church says:
• We honor the past, but we are not enslaved to it.
• We value tradition, but we value the mission more.
• We will never protect a practice at the expense of reaching people.
• We refuse to let comfort outrank calling.
• We are willing to change anything except the gospel.
Because the mission of Jesus is too important to be slowed by things that are merely familiar.
The Bottom Line
A sacred cow is not something biblical. It is something comfortable, familiar, and emotionally defended that quietly takes priority over the mission of Jesus. Healthy churches regularly ask: “Is this sacred to God—or just sacred to us?”
