The chief question: in what the freedom that makes choice free consists; Roman theologians disagree
The central point of the question appears to be where, strictly, the freedom lies that makes the will called free and in which the essence of free choice consists.
Theologians of the Roman Church are not entirely agreed on this. To make their differing opinions clearer, one must first set out the senses and distinctions of freedom that the schools employ.
Latin
XI. Quod autem videtur in hac quaestione praecipuum, illud est in quo proprie posita sit, illa libertas a qua voluntas libera dicitur, & in qua consistit ratio liberi arbitrii. Qua de re non omnino convenit inter Theologos Ecclesiae Romanae. Sed ut discrepantes eorum sententiae melius intelligi possint, primum tenendum est quae sint in Scholis usitatae libertatis acceptiones atque distinctiones.
