The freedom that names free choice is not freedom from servitude
The teachers of the Roman Church point out that the freedom under discussion, from which free choice takes its name, is not the freedom opposed to servitude, either literal or figurative.
Someone who is a slave by condition is not for that reason without free choice. Neither have those whom Scripture calls slaves of sin been robbed of it by sin.
Latin
XIII. Porro Doctores Ecclesiae Romanae notant libertatem de qua hic agitur, & a qua denominatur liberum arbitrium, non esse libertatem illam quae opponitur servituti, seu propriae seu Metaphoricae. Idque quoniam homines conditione servi non propterea carent libero Arbitrio; Neque etiam per peccatum eo spoliati sunt illi quos scriptura sacra vocat peccati servos.
