Guren no yumiya is an addictive song. The melody makes you feel badass all over.
Until the lyrics made me freeze. I have grieved the Spirit by listening to it over and over again.
This is the translated line (the culprit):
No matter how much you pray, nothing will change
What changes the moment is the will to fight
I'm a Christian and call me a Jesus Looney, but spiritual warfare is very real and the evil one is a wily creature. Beauty can be a tool of deception (the instrumental is great)
I have never seen the anime before, but I have read the wiki and there are themes like bravery. And how people with shortcomings and seemingly no talent can become heroes (Eren).
There is a cult that worships the walls that surround and protect humanity against titans, nude giants with deformed, barbie doll anatomy (some with perfect proportion and no skin) who eat humans for the heck of it (they don't seem to digest their meals) and believe the walls to be holy (they were torn down by the Colossal Titan later). The walls are built by man and not impenetrable! If the above lines were composed with this part of the anime in mind, it is more palpable. But still, the song on it's own, no matter the context, is offensive to me (cue the narrow mindedness label from anime fans).
These are the three things I know about prayer:
God says yes (prayers answered)
God says no
God does not reply (He has better things in store)
I'm aware that anime is a medium, not a genre, and I myself is an animation student. But anime comes from a place where Christianity is seen as just another interesting religion (and a minority of the population too). Hence there are (supernatural) elements that are likely to grieve the Spirit, as well as containing unbiblical values.
I cannot really judge the series as a whole since I'm a total stranger to it, but I have beef with guren no yumiya.
