Language is not essential for the cognitive processes that underlie thought

While not essential for thought, language is a very important tool in shaping and sharing thoughts.

Another related tool is religion (for emotions instead of thoughts,) which funnily enough faces the same divergence language does.

Right now society that calls itself "secular" simply does not understand the role of religion, and its importance in society.

To be clear, I don't belong to any religion, I am saying one needs to be invented for people who are currently "secular."

In fact, you have the disorganized aspects of religion already. All one needs to spot these are to look at the aspects that attempt to systematize or control our feelings. Mass media, celebrities for example.

Instead of letting capitalistic forces create a pseudoreligion for society, it's better if people come together and organize something healthier, intentionally.

Materialism is such a religion. It's sciency and emotion-free, so it appeals to the secular minds.

Holding materialism as an axiom, either directly or non-directly (through other axioms) could be called a "religion" (though at that point I'm not sure what couldn't be), and either way that could be considered bad.

Thinking some type of materialism is even mostly correct, with the sum over all mostly materialist theories being close to 1, isn't a religion at all.

In secular society art is the language for emotions.
