Rejecting Text Messages Galaxy S4?

[Epicnessx]

Do you really need an app in order to do so?
Or is there an option on the phone to reject/block text messages?

Sorry if I'm not supposed to repost but my other post was asking if it was possible to, and I want to know if it is without an app.

This is pretty much a double post. I'll close this thread and rename the other.
