BTW, as a former Catholic I can also say that this lack of knowledge is somewhat desired by the Church, i.e. enforced. Sure, you hear a short snippet of scripture during mass, but to my knowledge they never bothered to explain their theology, i.e. transsubstantiation, why the Pope supposedly has the authority etc.
It's not too surprising either, given that the CC only stopped reading the Bible in Latin (so that nobody would understand it) when Luther forced them to.
