Kneeling
Kneeling is a human position in which the weight is distributed on the knees and feet on a surface close to horizontal.
Kneeling, similarly to bowing, is associated with submission and obeisance. Kneeling is often used as a position for prayer, as a position of submission to God.
According to custom, the position of kneeling is assumed at different times in the services.
In some church buildings, pews are equipped with kneelers in front of the seating bench so members of the congregation can kneel on them instead of the floor. Although kneelers are less common in Orthodox church buildings, they do appear in some. There appear, obviously, where there are pews in the building, and often when the building was purchased from Protestant or Roman Catholic parishes.
