The next step is using a combined theory of sacrality by Eliade, Hoffman, Jones to browse through the fundamental of the rituals and the entire surface, while for the fundamental & expression form, the elaboration of architectural significance approach by Salura, Evensen, Peirce is being used, The analysis are based from the structualism approach that traces the existential expression from the surface expression in the Cathedral Church.
