Note, 1. Religion and loyalty must go together. As men, it is our duty to honour our Creator, to worship and reverence him, and to be always in his fear; as members of a community, incorporated for mutual benefit, it is our duty to be faithful and dutiful to the government God has set over us, Rom 13:1, Rom 13:2. Those that are truly religious will be loyal, in conscience towards God; the godly in the land will be the quite in the land; and those are not truly loyal, or will be so no longer than is for their interest, that are not religious. How should he be true to his prince that is false to his God? And, if they come in competition, it is an adjudged case, we must obey God rather than men. 2. Innovations in both are to be dreaded. Have nothing to do, he does not say, with those that change, for there may be cause to change for the better, but those that are given to change, that affect change for change-sake, out of a peevish discontent with that which is and a fondness for novelty, or a desire to fish in troubled waters: Meddle not with those that are given to change either in religion or in a civil government; come not into their secret; join not with them in their cabals, nor enter into the mystery of their iniquity. 3. Those that are of restless, factious, turbulent spirits, commonly pull mischief upon their own heads ere they are aware: Their calamity shall rise suddenly. Though they carry on their designs with the utmost secresy, they will be discovered, and brought to condign punishment, when they little think of it. Who knows the time and manner of the ruin which both God and the king will bring on their contemners, both on them and those that meddle with them?

For their calamity shall rise suddenly,.... And come upon those that fear not God, and rebel against the king and the state, and innovate in matters of religion; and especially that bring in damnable heresies, and, while they cry Peace, peace, and are pleasing themselves with their new schemes and prosperous success, swift and sudden destruction comes upon them, Pe2 2:1;

and who knoweth the ruin of them both? of those that fear not the Lord, nor the king; or of those who are given to change, and innovate in things civil and religious; and of those who meddle with them and join themselves to them: the ruin of themselves and families, in a civil sense, is great and inexpressible, who rebel against their prince, and endeavour to change and subvert the present government; and the ruin of the souls of men, both of the deceivers and the deceived, is beyond all conception and expression.

A warning against impiety and resistance to lawful rule (Rom 13:1-7; Pe1 2:17).
