Portuguese to English Law/Patents Law: Contract(s) Comittment of the Brotherhood (Compromisso da Confraria)

As a continuation to my previous query, I have some doubts regarding the last part of the following sentence (19th century Compromisso da Confraria in the Estado da Índia)

"O catálogo será confeccionado nos termos e pela forma marcada no regulamento e modelo que o acompanha, inscrevendo-se n'elle promiscuamente os confrades e devotos e designando-se esta qualidade"

My doubt here is to what exactly does "esta qualidade2 refer to in this context. Is it the "forma"? Or is it referring to "promiscuamente"? Or to anything else?

I would be grateful for any assistance here!
