The government is explicitly forbidden from instituting a national religion, showing favoritism towards any religion, or demonstrating a bias either for religion in general or against it.
From this, it appears evident that they should refrain from drafting or interpreting laws in any way that might establish a national religion, grant preference to a specific religion, or exhibit a bias either in favor of religion overall or against it.
Given that Congress—the body responsible for crafting all laws—is barred from creating laws that would do any of the above, it stands to reason that the Supreme Court must also avoid interpreting laws in a manner that:
- Institutes a national religion,
- Displays favoritism towards a certain religion,
- Promotes religion over non-religion, or
- Advocates for non-religion over religion.
This suggests that the Supreme Court should steer clear of making any rulings that directly involve religious matters.
