Whether three accompanying conditions of an oath are suitably assigned, namely, justice, judgment, and truth?

Objections

Objection 1 : It would seem that justice, judgment and truth are unsuitably assigned as the conditions accompanying an oath. Things should not be enumerated as diverse, if one of them includes the other. Now of these three, one includes another, since truth is a part of justice, according to Tully (De Invent. Rhet. ii, 53): and judgment is an act of justice, as stated above (Question [60], Article [1]). Therefore the three accompanying conditions of an oath are unsuitably assigned.
Objection 2 : Further, many other things are required for an oath, namely, devotion, and faith whereby we believe that God knows all things and cannot lie. Therefore the accompanying conditions of an oath are insufficiently enumerated.
Objection 3 : Further, these three are requisite in man's every deed: since he ought to do nothing contrary to justice and truth, or without judgment, according to 1 Tim. 5:21, "Do nothing without prejudice," i.e. without previous judgment [*Vulg.: 'Observe these things without prejudice, doing nothing by declining to either side.']. Therefore these three should not be associated with an oath any more than with other human actions.
