Michael, 48, was released from a Viennese hospital last month after clear signs of improved health and took to Twitter to denounce the group, which some critics argue are not Christians.
"Did you know that while I was fighting for my life in Austria there were a bunch of those lovely American 'Christian' organizations, who call themselves 'Christians for a Moral America', who were actually taking the time to pray for me to die," Michael tweeted.
After posting CP's article for his followers to see, the "Freedom" singer continued venting his frustrations at CFAMA.
"Now don't get me wrong, I know for a fact that many devout Christians, such as the ones I work rest and play with on a daily basis, are truly wonderful, kind hearted men and women who take the best parts of that religion and live admirable, generous and loving lives," he wrote.
"But In my opinion, and i think made evident by those who prayed for my death, there are others who use their twisted interpretations of ancient scriptures as a pathetic excuse to be.......wait for it, wait for it.......!"
Michael then used profanities to describe the group.
CFAMA, who also has a Facebook page, had initially posted a series of shocking tweets when Michael was hospitalized, but they have since been removed.
"Pray for George Michael's demise. He has chosen a satanic lifestyle and must meet an appropriate end," one tweet read.
Another tweet read, "Once George Michael bites the dust, it'll be the perfect time to roll out new anti-sodomy ads. This lifestyle is clearly dangerous."
Many are outraged, particularly Michael's religious fans who have taken to social networking sites Facebook and Twitter to condemn CFAMA.
Critics are urging for the public to disassociate the Christian faith from CFAMA, arguing that the group's values do not truly reflect that of Christianity.
