On the question of finance, there was historically a prohibition on usury in Christianity. This was worked around by the triple contract / Contractum trinius.
I have been told that something comparable happens in currently existing Islamic finance: people devise clever schemes that are technically acceptable, though not really in the spirit of what was intended, so they replicate lending-at-interest without technically doing so. (I believe there may also be some regulatory flexibility in choosing which religious scholar you submit your scheme to, being able to select one that is known for looking favourably on such proposals.)
I believe that there are circumstances in which financial services that are in tune with the spirit of some of these rules (rather than just within the letter of them) could be desirable. But people do seem to have a habit of finding ways around them.
