[ WP ] There are rituals that summon demons . Why are there no rituals that summon angels ?

I replaced the chalk circle drawn in a damp basement with one drawn onto a rock above an ocean-side cliff in broad daylight. The nine candles were replaced by seven freshly cut roses. The Dark Book of Rituals was now a family bible, holding many years of church-going writings and notations by many generations of my family. 
 
 `` Well here goes nothing,'' I spoke into the air with a smile. If I was right I had reversed just about everything from a normal demonic summoning ritual. I had just figured out how to reverse the sacrifice part. I planted a seed in a small patch of dirt in the center of the stone. Instead of taking a life I was starting one, `` Come forth o' angels of heaven!'' I chanted over and over. 
 
 `` What is it you want, exactly?'' The voice speaking from behind me startled me and I nearly jumped out of my skin, `` I was in the middle of tea and then here I am.'' She looked around, her wings were down in what I thought was a defensive posture, `` Quite rude, if you ask me. How would you like to be in the middle of a bath and blam, suddenly you're sitting in a circle of insects that summoned you? You would n't like it at all, I tell you.'' 
 
 `` Are you an angel?'' I asked her, the smile on my face was mixed with emotions. I was elated but guarded at the same time, especially with her attitude. 
 
 `` No, I'm a chicken,'' She rolled her eyes and looked around then held her nose, `` Just what are you humans burning nowadays? This place stinks. I see that you think you're pretty clever with this circle thing. Not a pentagram? Oh, a heptagram! Clever again. Not bad for an ape-born.'' 
 
 `` So, what is heaven like?'' I asked, trying to ignore her rudeness and salvage something from this summoning. 
 
 `` Think this,'' she said gesturing to the world around her, `` Except the exact opposite. Wow, when the Old Man let things run their course I did n't expect things to go completely to shit. Where are the unicorns?'' 
 
 `` Unicorns?'' I raised an eyebrow to see if she was pulling a fast one on me, `` There are n't any.'' 
 
 `` Ah, you ape-born kill and eat them all in some savage ceremony?'' She asked and laughed, `` I'd expect as much. Always thought the Old Man should have created you with a few more brain cells. He said free will would take care of that, but look at the mess you've made.'' 
 
 `` We were created in His image,'' I said, showing her the bible, `` It says so right here!'' 
 
 `` Oh that's rich!'' She said and laughed heartily, `` And who wrote that? I bet a grasshopper would imagine the Old Man as a giant grasshopper. No, He's much handsomer and smarter than you lot.'' 
 
 `` Can you please leave?'' I asked her, slamming the bible shut because I did not want to hear any more. I suddenly realized why there were no rituals for summoning angels. They were assholes.
