Christians perform many rituals; sometimes using spell components, incense, bible, cross, rosary, or one of the many other tools.  Sometimes with somatic jesters like, clasping hands, bowing heads, waving hands in the air, kneeling, or tapping their hand on a spell recipients forehead.  Of course; almost all Christian rituals or spells involve verbal components or chanting.  Some spells that Christians cast, don't involve any of those three components, but on what I'll call a focus.  They focus their spell through their Chi, Faith, or God.  Some rituals or spells they use attempt to do some of the following things:

   Blessing of food (more than just giving thanks to god) ie.. food purification.
   Mind alteration spells, "I pray that Joe Schmoe, will change his mind and not do the action he is planning on doing".
   Love spells "Please God, I beg you, that he will take me back."  (usually cast on ex's.)
   Protection spells, usually cast on loved ones going on trips.
   Fortune spells, like prayer for winning lottery,(gambling is wrong according to the bible, not going there though), or aid in bills.
   Healing spells,  usually done in groups. (sometimes known as faith healing.)
By use of this magic, christian will rationalize their actions, by calling the results miracles. (see side for definition of miracle)

   By defination, a miracle cannot be summoned, but yet christians, through their rituals (prayers) attempt to invoke the spirit of god, and summon these miracles.
