It simply means our nation is no longer governed, led, inspired, or led by Chritians, Chrstian ethics, or the Ten Commandments.
The "bowing down to liberalism" actually began in 1925 (Scopes Trial - Evolutionism ~vs~ Creationism) when the American bought into evolution (now taught as a religion).
Christians today are considered "Neofascists" and "extremists" in American and it won't be long until many of the major precepts (e.g., homosexuality is a sin and unacceptable lifestyle) will be illegal.
Was the nation governed, led or inspired by Christians, Christian ethics or the Ten Commandments before the Emancipation Proclamation?
