I think Christianity does incorperate magick. though it may not be looked at the same.
Prayer to God or saints ect...esentually the same as some magick based reiligons casting a spell. You are announcing what you want and asking for your higher beings help inattaining it.
In some christian denominations, you can light a candle for prayer...same as using candle magick.
I know in the catholic faith they will after the...uhm...long reading by a perish member give certian things we should be thankful for, and then ask to pray for the sick members or anyone who is sick. Same as some healing magick. You are praying for them to be well and asking for the help of god to heal them.
Christianity has a lot of magick in it's practice. It just isn't called magick ;)
It is referred as witchcraft.. *_* Most Catholics use it.. (magick) I am a catholic.. they use rituals, yearly.. If you ever being into a catholic church and into their main masses,, you will find it curiously creepy.. (all related to rituals and spells and magick) -_- I say it all the time.. they all witches hahahaha.
my famly is christian and im also i a catholic high school (even though im wiccan) and through my observations they practice magick too... they just dont notice. for example our morning prayers which are over the P.A system sounds and is CREEPILY a chant/ spell being cast by everyone in the school at once.
