If someone said that modern religions are hardly different from old like European pagan beliefs and thinks that all spirituality regardless of even it’s theistic or non-theistic is obsolete a/o there not neccesary from now on,what do I say to them?.
Rather than reply, why not listen? Why not take an honest look at why the partially educated individuals who are getting their limited understanding from well-educated professors believe as they do?
Then suppose that they are right, so what? What does that mean?
The knee-jerk reaction is to think,
Hey! This is threatening my belief in God! And that is exactly what it does. But does the threat to Christian theology, to your personal beliefs, mean that there is no creator? More to the personal point of relevance, does it mean that you have no soul and will not survive your body’s death?
Not necessarily.
The argument you face means simply that theology has not been updated in a long time, which is absolutely true.
Galileo tried to get the Church to reconsider its theology in light of scientific evidence 350 years ago, and the Church refused to do so. That’s not a lie, so waste no time denying it.
Since then, science has learned a great deal about the core nature of reality. Some of its data is legitimate (the evidence of a 13.5 billion year old expanding universe, the evidence of biological evolution, quantum effects in physics), and many of its theories are bogus (the Big Bang theory, Darwinism, and the Copenhagen interpretation of quantum mechanics).
However, throughout the interesting give and take conversations going on within science, the Catholic Church, once a leader in such things, has joined all other religions— by taking comfortable, very old seats on the sidelines.
Were you to be able to admit these things, which your indoctrination will render impossible, you could say to your antagonist,
You are right. Those of us who believe in a Creator need to find a way to fit our understanding of that Creator into the reality of science.
