In a city with many shuls, in what way should we think about the individual shuls?
a) They are “service” (no pun intended) providers and I will take the services as they suit me best. Even if I take membership of one or more shuls, that does not limit my use of the other shuls.
b) Once I become a member of one shul, I have an obligation towards it to organise my life around its timetable to preferably go to its shiurim and other events.
There are obvious advantages of a community: people take an interest for and care for each other; if I am not in shul people will check to see if I am well etc.
The ideal answer would contain some form of source material – if not responsa, at least stories of Gedolim.
