It is an intentional design restriction that secret societies need to get people to their guildhouses. There are several reasons for that. One that it ought to be a bit tricky to run a secret society, another one is that this counters the advantage of having hidden guildhouses (following nobles travels is one way to find out where they likely are) and one that it simply fits the mood. Recruiting a new member personally would introduce him only to the recruiter, not the rest of the society. A religion is public, it doesn't have the secrecy problem.
