If you define religion as any organized religion, then my answer would be none.
However,
If you define religion as independantly absorbing like a sponge:
that which is truly good and eternal,
that which is the understanding of life and death,
that which is the knowing of both good and evil,
that which is the causation of blessing and cursing,
that which is the love of knowledge, and the painful hindsight of ignorance,
that which is the drive to excel, and the weakness to sin,
that which impels us to improve, and that which hampers our progress,
that which makes us god-like, and that which makes us mortal,
that which teaches us patience, and that which helps us to take decisive action,
that which is the striving for understanding of everything,
that which urges us to immortality,
Then my answer would have to be:
Christian, as in individually striving to be like Christ Jesus.
BA- It's a multiple choice quiz, you know.
