Sacred architecture, at its best, should be an experience that transports the perception of the human eye to a new form of consciousness.  Church buildings, by definition, are a specialized space created for the purposes of contemplation where Critical Reason and Revelation are joined in the human mind. The form of the structure should inspire the practice of prayer by means of visual stimulation. This is achieved, by combining both movement and theatricality, using natural light as the primary medium in creating spatial divinity. How light enters into the space and is thus filtered and defused by its architectural elements, determines largely the emotional experience of the interior. The Interior effect of the church should be that of a prism combining intense colorful light directed from above adding the dramatic use of luster, highlights, and deep shadows at specific moments and places. The carefully planned combination of these elements within the space should produce an experience of visual ecstasy that transports the human psychological perception to a different reality. The realm of the divine is a state that is momentary experienced by the mind trough rituals. In the in certain ancient religious cultures, art was used in order to achieve a level of altered consciousness. For example, one can see the beginning of this trend in cave painting dating back to Aurignacian period. Therein the darkness of a cave, designs where painted upon the uneven surface of the walls producing a spatial condition that created a specialized space. This space was a setting for exploration of the unknown regions human mind because it induced powerful psychological effects and hallucinations. Similarly in the Christian tradition, the ancient rituals of the church are framed by art and architecture. Iconography is presented to us within architectural space inducing similar effects to those of its prehistoric precedence. Sacred objects acquire a sense of veneration.  Through-out the history of the church, art and architecture has been employed to provide visual proof and definition to the unseen things.  In this, art and architecture becomes an instrument by which the theological principle behind the invisibility of the divined is conveyed to the public. The Architectural form thus serves multiple functions and accomplished different things by teaching theological principle, inspiring the faithful with psychologically meaningful visual effects, and providing an envelope of shelter in which these religious rituals can take place
