Bronsted Versus Lewis

I remember Professor Lavelle mentioning that either Bronsted or Lewis is a more general classification meaning that all acids and bases are one thing but not necessarily the other. Which term is more general, Bronsted or Lewis?

I believe it is that all Bronsted acids and bases are Lewis acids and bases, but not all Lewis acids and bases are Bronsted acids and bases.

One of the UA told me they were the same thing.

I believe Bronsted is more general, since it refers to being an electron pair donor or acceptor, while Lewis regards being a proton acceptor or donor, which some acids and bases may not have.

The Lewis definition is more consistent in classifying most acids-bases, since a molecule might not have hydrogen to donate for the definition of a Bronsted acid. However, my TA said, at least for now, the Bronsted definition will be primarily used (i.e. for writing chemical equations in acid-base reactions), unless told otherwise.
