An atheist friend of mine posted this
“there have been 3000 gods so far but only yours actually exists. The others are silly made up nonsense, but yours, yours is real”
Of course hes speaking sarcastically. What are good arguments to make against this. The idea that because many gods have been proven false over the years therefore God is false as well
There actually is another good answer to this. Christians rarely use it, but it’s founded deeply in the teachings of St. Paul and the other early Fathers of the Church.
The argument your atheist friend makes is based on both a false understanding of the historical beliefs of the Church, and the difference between a “deity” and God.
The historic view of the Church has been that the thousands of gods the pagans around them and by extension, in the rest of the pre-Christian world) worshipped were false gods, but not in the sense that they don’t exist. The early Fathers of the Church believed implicitly that there were spiritual beings that were worshipped in the temples of the pagans, and that they were fallen spirits, or as we term them, demons. Malign spiritual beings of great power, but nothing like the powers of the one true God, and mere caricatures of God’s nature and essence.
As Paul said, “What the heathen offer, they offer to evil spirits.” (1 Corinthians 10:20).
I would say that the test for whether such a deity was an evil spirit would be to look at their teachings and their demands. It’s not hard to say that the cult of Thor that demanded the sacrifice of young men under an oak tree, or the cult of Moloch that demanded the sacrifice of infants, or the Aztec gods that demanded the hearts to be torn out of captured prisoners, or countless other pagan idols, represent demonic powers at work.
The modern deities we worship - money, power, prestige, nationalism, and so forth could be considered the teachings of the old deities in new guises, and they demand their own blood sacrifices of a sort.
Other, more gentle, non-Christian religions could be simply the inventions of men who were trying to work their way towards an understanding of God, however imperfectly. But they are the teachings of men, not God.
So the answer to your friend is that Christians have historically believed not that the other pagan gods that men have worshipped are “silly, made-up nonsense”, but that they are real entities, who exist in enimity towards us. Most of them have lost their holds on men, or adapted to fit the temples of the modern era.
We believe there is only one spiritual entity worthy of the name God, and that all other deities are false gods that do not compare to Him in nature.
If nothing else, it may be an argument that he hasn’t heard before.
