Catechesis Pro Advltioribvs Scripta, De his potissimum capitibus

However the matter may be, it is certain from the divine scriptures that God, [explaining] what kind of mind he has toward men, and what he wants to be done or omitted by them, first indeed explained and promulgated [it] through distinct chapters, then wrote those same things, indeed with his own finger, with a stylus most divine of all, onto stone tablets, and finally ordered [them] to be hidden in the ark, so that they might not be abolished or perish, and thus he commended his Law through Moses to his people most diligently.

The Law is distinguished into two tablets.

I. How then is this Decalogue of God usually distinguished?
R. Into two tablets and Ten commandments, so that the prior tablet contains four chapters or commandments: the posterior, truly, six precepts.
I. What do those two tablets contain, or to what do they pertain?
R. The prior pertains to God and his worship, containing the duties owed to God. The posterior looks at men, and hands down to us the duties owed to our neighbors. To which ten laws, indeed, all other laws, however wide and copious, scattered throughout the sacred book, can be referred.
