The big question is whether Christian consciousness possesses the ability to expand, develop, and grow.
If it doesn't, then Christians already have everything they need to think about, understand, and relate to God, Creation, themselves, and others.
If it does, then how Christians think about, understand, and relate to God is open to further expansion, development, growth.
The two possibilities inevitably lead to very different "sets" of metaphysical assumptions, both of which are Christian.
The major difference between the two sets of assumptions comes down to a matter of meaning and purpose.
The question of Christian consciousness is the question of what Christianity is ultimately aiming for.
