Question about your interview actually in 70

Hello, Rabbi Michael Avraham!
In your interview in the 70s, you said (correct me if I’m wrong in the wording) that anyone who is rational must be religious and within the framework of religion. Religion is the one that provides the best response to rationality, and arguments that are not religious are not rational enough and lack many things.
I would be happy to explain and if possible refer to sources, etc.
