Republican presidential front-runner Donald Trump has finally revealed who he really is—anything but the defender of conservative Christians that he claimed to be, according to acclaimed biblical scholar, Jewish author and radio host Dr. Michael Brown.

Writing for Charisma News in his "In the Line of Fire" column, Brown says Trump unmasked himself when he appeared on the Today Show on Thursday and answered questions on abortion, North Carolina's Bathroom Privacy Act and transgender rights.

Asked if he would like to change the Republican Party's position against abortion—which rejects even such exceptions as rape, incest or serious threat to the life of the mother—Trump replied matter-of-factly, "Yes, I would, absolutely, for the three exceptions. I would."

Brown concedes that "the questions of rape, incest or the life of the mother are terribly painful questions that deserve thoughtful and compassionate answers, especially from other women."

However, Trump's statement is far from what a true a pro-life champion and defender of conservative Christian values would say on this issue, Brown says.

He then cites some of the more hard-hitting public reaction to what Trump said.

Kristan Hawkins, president of Students for Life for America, asked: "Does he [Trump] want to put an exception into the platform saying it's OK to murder a 2-year-old child whose father is a rapist, too? Or is he only OK with it as long as the child hasn't been born yet?"

Brown also quotes Rebecca Kiessling, a woman conceived by a rape, who said: "Donald Trump has the audacity to suggest that the Republican grassroots has been wrong to believe in protecting innocent children like me who were conceived in rape. My message to Donald Trump, and others like him is this: Punish rapists, not babies!"

After making known his position on abortion, Trump blasted North Carolina's HB2, the state's new bathroom privacy and security law designed to protect women and children.

"North Carolina did something that was very strong, and they're paying a big price. There's a lot of problems," the New York billionaire said.

Trump approves of transgenders using the bathroom of their choice, even if this would adversely affect other people.

Brown says this is contrary to the position of conservative Christians "who have raised their voices the loudest in support of bills like HB2, standing up for the safety and privacy of women and children and not wanting heterosexual predators to use the loophole of 'transgender rights' to prey on our wives, children or grandchildren."

Brown commends Sen. Ted Cruz, Trump's key rival in the Republican presidential contest who voiced strong support for HB2.

He then quotes Cruz as saying in his response to Trump's comment on the North Carolina law: "Donald Trump is no different from politically correct leftist elites. Today, he joined them in calling for grown men to be allowed to use little girls' public restrooms. As the dad of young daughters, I dread what this will mean for our daughters—and for our sisters and our wives. It is a reckless policy that will endanger our loved ones.

"Yet Donald stands up for this irresponsible policy while at the same time caving in on defending individual freedoms and religious liberty. He has succumbed to the Left's agenda, which is to force Americans to leave God out of public life while paying lip service to false tolerance."

Brown says conservative Christians should be "more comfortable" with Cruz's position on the matter that with Trump's.

The author says he respects people who continue to support Trump, even though they believe he's not really a Christian or a real conservative, on the belief that he's the best leader who could fix America's ailing economy and unsecured borders.

"But please don't look to him to be a defender of conservative Christian values or a protector of religious freedoms," Brown tells these Trump supporters.

"Barring dramatic divine intervention in his life, you will be sadly disappointed," he says.
