So I set up a 4 digit passcode and reply with message is turned on. However, when someone sends me a text and I slide it to reply, I have to enter my passcode. Why?

Because anything that requires you to use an app requires your iPhone to be unlocked. Text messaging uses the Messaging.app. Since you set up a passcode to unlock, anytime you unlock you have to enter the passcode.
You can ask Siri as long as you have enabled Siri whist locked. Siri will be able to sent a message and make a call whilst your phone is locked. If you haven't enabled Siri whilst locked you go to Settings > General > Passcode Lock > Siri (switch slider).
