Unde de bello iusto duo gratia Dei declaremus salutis documenta in precedenti sermone omissa, scilicet: 1) Primum quid agere debeat capitaneus vel campiductor; 2) Secundum quid facere debeat miles seu propugnator.

Therefore, about just war we can illustrate (with God's grace) two useful teachings omitted in the previous sermon: 1) The first concerns what the captain, i.e. the one who trains troops, should do; 2) The second concerns what the soldier, i.e. the one who fights, should do.

This sermon is part of a group (sermons 21-24, from Tuesday after Oculi to Friday after Oculi) developing the topic of the fifth commandment.  This sermon continues the discourse begun in the previous one (T21/4 Wednesday after Oculi).
