At a glance it doesn't seem you're contradicting me but that faith stipulates following Biblical instruction. That describes the religion in practice, anyone that dons faith would do that (or portend to) as faith encapsulates all those ideas.

The notion that people should do good for its own sake doesn't really change the fact that it's the ticket for Catholicism. Conversely in, say, Calvinism nothing you do can guarantee Salvation.
