Many Reformed oppose liberty only to compulsion and define it as freedom from compulsion
They do not all explain in the same way what the freedom consists in that makes man free in acting and gives his choice the name free.
To begin with, a good many of the Reformed teach that the freedom by which man is said to have free choice is not set against bondage, or against necessity as such, but against compulsion. They mostly talk as if compulsion were the only thing that destroys freedom, and they describe freedom as exemption from compulsion.
Latin
IV. Verum non explicant omnes eodem modo qua in re sita sit libertas, ratione cujus homo liber in agendo dicitur, & a qua denominatur liberum ejus arbitrium. Et primo quidem ex Reformatis non pauci, libertatem illam cujus respectu homo dicitur esse liberi arbitrii, nec servituti, nec necessitati simpliciter opponi docent, sed potius coactioni. Ac plerumque loquuntur quasi coactio sola libertatem perimeret, & libertatem describunt immunitatem a coactione.
