Dr. Paul Church says that he was terminated by the Beth Israel Deaconess Medical Center in Boston, Massachusetts, because of his opposition to the LGBT lifestyle based on his heath and Christian-based beliefs.
"They chose a social agenda that they wanted to promote," the 66-year-old urologist told FoxNews.com.
Church opposed the hospital's support of Gay Pride Week and LGBT Achievement awards, which he compared to promoting smoking.
The hospital's medical executive committee voted to expel Church in December 2015.
The hospital told FoxNews.com that Church's actions were "inconsistent with BIDMC's established standards of professional conduct."
The hospital didn't go into detail, but Church admitted to sending emails to fellow staff, including one in response to a pro-gay event hospital email.
Church wrote: “Behaviors common within the homosexual community are unhealthy and high risk for a host of serious medical consequences, including STDs, HIV and AIDS, anal cancer, hepatitis, parasitic intestinal infections, and psychiatric disorders. Life expectancy is significantly decreased as a result of HIV/AIDS, complications from the other health problems, and suicide.”
Some of the hospital staff members were offended by Church's emails, which included Bible verses.
The hospital formed a peer review committee in 2011, which accused Church of violating hospital harassment policies. Church was told by the committee to stop communicating his opinion on sexual orientation with the staff, noted NewBostonPost.com in 2015.
Church also posted three comments on an internal hospital web page in 2013 and 2014 in response to the hospital's involvement with Boston's gay pride parade.
Church included two Bible verses, Leviticus 18:22, which calls homosexuality an "abomination," and Romans 1:26-29, which condemns homosexuals and lesbians.
Richard Mast, Church's lawyer at the Liberty Counsel, which defended anti-gay Kentucky clerk Kim Davis, told FoxNews.com that Church has no more options at the hospital, but can still practice medicine.
Church asked the hospital not to send him emails for pro-gay events, but he and Mast say the emails kept coming.
"Dr. Church has objected to the promotion of homosexuality because of the inherent dangers of homosexual activity," Mast told the Boston Business Journal in 2015. "... Dr. Church has repeatedly made known his objections [to homosexuality] in a medical capacity, and his wishes that he not be the recipient of these [LGBT events] based on his Christian-based beliefs. Both of those requests have been ignored."
