What is the difference between the centralists and the federalists in Mexico?

The Centralists were generally conservative and favoured a strong central government in the viceregal tradition, a paid national army, and Roman Catholicism as the exclusive religion. The Federalists favoured limited central government, local militia, and nearly autonomous states; they tended to be anticlerical and opposed the continuance of colonial fueros, which gave special status to ecclesiastics and the military and exempted them from various civil obligations.
