A brief perusal of a few atheist web sites reveals a new asininity that appears to be popping up a lot recently. Militant atheists tend to be rather young, or at least immature, and so it the phrase “I only believe in one less god than you” is considered to be a brilliant and witty rebuttal to two thousand years of Christian theology.
This reveals a great deal of ignorance as to what Christians actually believe. There is nothing existentially monotheistic about the commandment: “Thou shalt have no other gods than me”, and it also flies in the face of Jesus and Paul’s statements with regards to the god of this world.
The truth is that Christians, like the pagans of yore, believe in the existence of many gods. The difference is that we worship only one, the Creator God, who sent His Son to die for us.
