One may easily simplify the Torah, but such simplification of Catholicism is not possible.  The complexities of the faith and tradition require lengthy study of many texts, preferably in the original latin, and constant reference to the catechism.  To be a true Catholic, and thus a true Christian, one must spend rigorous hours of study.  Perhaps after study there may be time to do a little something for one's fellow man, but even to adequately understand what it means to love one's fellow man requires much study and exercise of the intellect.  Of course, as a default, one may always simply obey all commands made by the nearest member of the clergy.
