Despite extreme backlash from the community, a private Christian school in Florida is not backing down from a long-standing policy that asks students to refrain from sexual behavior outside of marriage as well as kicking out gay and trans students.

“If I backed down from something like this, I’m abandoning what God has said is the truth. I …. kind of rack my brain to like, ‘How is this hard for people to understand? This is what God said.’ This is one of the many reasons we have a Christian school, and we’re not going to abandon this policy. God has spoken on these issues,” Grace Christian School Administrator Barry McKeen told Fox News Digital in a phone interview Sunday.

The school doubled downed on its commitment after outrage surfaced over an email McKeen sent to the school community earlier this summer highlighting that students will only be identified by their “biological sex” and saying that students who are found “participating” in gay or transgender lifestyles will be asked to “leave the school immediately.”

“We believe that God created mankind in His image: male (man) and female (woman), sexually different but with equal dignity,” the email McKeen sent to the school community in June reads, according to NBC News.

“Therefore, one’s biological sex must be affirmed and no attempts should be made to physically change, alter, or disagree with one’s biological gender — including, but not limited to, elective sex reassignment, transvestite, transgender, or non-binary gender fluid acts of conduct (Genesis 1:26-28). Students in school will be referred to by the gender on their birth certificate and be referenced in name in the same fashion,” the email continued.

McKeen said he felt the need to send the email as a reminder to parents that “although this is being celebrated and encouraged by the country, it is condemned by God. And at this school, we’re gonna follow God instead of man.”

The school has not had to kick anyone out yet for violating the policy, but one mother did say she has pulled her lesbian daughter following the email. According to Fox News, she told the media that even though there are “loving teachers at that school” and she respects the school’s opinion, she removed her high schooler for the girl’s “wellbeing.”

“We don’t expect any of our students who are not married to be sexual, whether it be bisexual, heterosexual or homosexual. I tell people, if a kid came in the doors, exclaiming how he was having sex with his girlfriend, that student would be expelled, as well,” McKeen said.

According to Fox News, who held an interview with the school administrator, McKeen said that he and his family have since received death threats following press coverage of his email on the policy. He has had to increase on-campus security since.

He added that the school was forced to have a “massive law enforcement” presence on Friday and hired armed security guards to bolster protection for the students from any potential threat.

McKeen published a response video following the news coverage last week and said that he was prompted to do so because people were portraying the school as “hateful.”

“We are not a hateful group of people. We don’t hate students who are of a particular persuasion,” he said in the video.

McKeen said he was shocked that the policy would even make national headlines and argued that the outrage from some across the country is indicative of America moving away from God and Christianity.

“It’s kind of been beyond me that this has blown up to what it is, like you’re shocked that a Christian school has this policy?” he said.
