Matthew Poole and continuators on Titus 3:1

1 PUt them in mind to besubject to principalities, and powers , to obey magistrates , to be ready to every good work .

All the supreme secular Powers at this time, were Pagans, and no friends to the Christians in their Dominions, which might be a temptation to the Christians to rebel against them, or at least not to yield them so free, universal, and chearful an Obedience as they ought; therefore the Apostle presseth this Duty upon them, and that not here only, but Rom. 13.1. 1 Pet. 2.13.

By the former term he might understand the supreme Magistrates, by the latter, those inferiour ranks; as he expresseth himself more particularly, 1 Pet. 2.13, 14.

To be free, and prepared to every work which is acceptable to God, and honourable in it self.
