Not exactly a Christian undercover but a shocker as a standard bearer for Anglicanism is English author and columnist Peter Hitchens, the brother of recently deceased arch-atheist Christopher Hitchens.
Christopher's last attack on religion titled "God is Not Good" earned Peter's one word review – "misguided." Conservative pundit Peter attacks sex education and the relaxing of the war on drugs as a result of his evolved Christian beliefs but firmly upholds the traditional family, the King James Version and the rule of law based on Christian faith. Like his brother, controversialist Peter has earned rebukes – notably from Prime Minister Cameron for calling for the dissolution of the Tory Party.
When asked to explain the difference between him and brother Chris, Peter replied "attitudes towards the existence of God." Christian dissent doesn't get much simpler than that.
