The Orthodox and Catholic Churches spirituality place importance on the use of human senses such as sight and on the use of beautiful things. Catholic spirituality often involves the use of statues and other artistic representations, candles, incense, and other physical items as reminders or aids to prayer. The Orthodox Churches also use candles, incense, bells, and icons, but not statues. Orthodox and Catholic worship also makes use of movements, such as the Sign of the Cross, made by each person touching first the forehead, then chest, one shoulder, then the other shoulder. There is also bowing, kneeling, and prostration in Catholic and Orthodox worship.
