what i've been taught vs what i've been "taught"

what?
i was talking with my wife about this, talking about our earlier christian walks, and the churches and everything
iwe were talking about, how the churches were, and how we were taught some things but then the actions would teach us opposing things.

for example, the idea that all sin is the same. we were taught that, we read the bible and people would make a point of saying that all sin is the same. then people would be seriously looked down upon if they went out and got drunk but a lot of other sins were overlooked or weren't looked so badly at.

there were a number of things that i 'learnt' which contradict what the bible teaches me about things
