2) Is the proposed custom fitting for the community in question?
3) Does the proposed custom facilitate and/or enhance the liturgy, drawing people deeper into the liturgy? Or does it simply draw attention to itself, limiting its appeal to a select few within the community, while leaving the majority of the faithful cold as to its meaning?
