I live in a very religious state, and the communities surrounding me are all based in said religion. It isn't Catholicism or Christianity, but, it's still based in somewhat similar beliefs.
I personally don't practice it or believe in it, but the presence of it's influence in my life has made an impression. I'm intrigued by the study of angels, demons, and other impressions brought about from certain religions, but I've always stuck to the hierarchy of angels. The book De Coelesti Hierarchia (On the Celestial Hierarchy) always fascinated me, and seraphim are a highlighted point of intrigue. They seem to be a somewhat universal entity in western religions, but the depiction of their presence varies with each different scope on what people believe. The concept of a seemingly beloved, but fearing entity suffocated by its own holy flames is an interesting idea, that it might snuff itself out if it burns too brightly. Or too strongly.
Also, as for my icon, I really enjoy Neon Genesis Evangelion c: I loved that animation sequence near the end of the season, and I think the biblical themes mirrored in the show were fitting to the username haha
