One of the U.S. Constitution's difficult balances is found in the freedom of religion clause of the First Amendment:
“Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof …”
What happens when those two values conflict?
That is the issue with the controversy over whether religiously-affiliated organizations should be required to offer free coverage for contraception in health insurance plans made available to employees. Those opposed — most notably Catholic organizations — claim that this requirement would violate their freedom of conscience. Those who support it claim that exempting religiously-affiliated organizations would establish a religion over the rights of individuals.
