What behavior, living in buildings owned by the Church while doing the job the Church has asked them to do? Wearing the uniform of their position while performing its duties?
Religious vestments and habits are the opposite of “worldly”: they are intentionally unworldly, that is, not what regular people are wearing. A suit and tie, or hipster gear, or randomly-selected Salvation Army items would be “worldly,” although not necessarily unsuitable to the roles of the people who choose that clothing.
“What behavior, living in buildings owned by the Church while doing the job the Church has asked them to do?”
Living the high life while purporting to represent the One who had no place to lay his head.

There are no Christian uniforms/costumes. It is pagan.

Pagan practices like this are worldly.
Did Jesus wear religious vestments?
Seems to me that John the Baptist wore *unworldly* garments but I don't think camel's hair would thrill a lot of those already accustomed to the finer type.
