LYNCHBURG, Va. (TheBlaze/AP) — Former Florida Gov. Jeb Bush is condemning the Obama administration's use of "coercive federal power" to limit religious freedom as he courts Christian conservatives ahead of a likely presidential run.

But he took a distinctly moderate tone even as he invoked Christianity.

The Republican White House prospect lashed out at the Democratic president's administration for "demanding obedience in complete disregard of religious conscience" as he delivered a Saturday commencement address at Liberty University, a Christian institution founded by the late conservative culture warrior Rev. Jerry Falwell.

More broadly, Bush said "the Christian voice" isn't heard enough in the world.

Bush also tweeted scripture to Liberty students.

On Twitter, some praised Bush for his moderate tone.

In @LibertyU speech, @JebBush works to show that he can talk about issues of religious freedom without alienating half the country

People also noted Bush was approaching issues in different ways from many conservatives.

In big, affirming speech about Christianity at Liberty, Jeb Bush makes no reference to traditional marriage. Very intriguing.

Others interpreted Bush's appeal to faith as a "dog whistle to anti-gays."

Some just rejected Bush's appeal outright.

Bush is preparing to enter a presidential contest that includes Republican competitors considered far more popular with the GOP's religious right. They all criticize Obama's health care overhaul which requires some religion-affiliated organizations to provide health insurance for employees that includes birth control.
