1. Spiritual in the rule, revealing and regulating it, viz. not any principles of state policy, parliament rolls, any human statutes, laws, ordinances, edicts, decrees, traditions, or precepts of men whatsoever, according to which cities, provinces, kingdoms, empires, may be happily governed: but the holy Scriptures, that perfect divine canon, wherein the Lord Christ hath revealed sufficiently how his own house, his Church, shall be ruled, 1 Tim. iii. 14, 15; and all his ordinances, word, sacraments, censures, &c., shall therein be dispensed, 2 Tim. iii. 16, 17. (See chap. IV.) Now this Scripture is divinely breathed, or inspired of God—holy men writing not according to the fallible will of man, but the infallible acting of the Holy Ghost, 2 Tim. iii. 16, with 2 Pet. i. 20, 21.
2. Spiritual in the fountain or author of this power, whence it originally flows; it being derived, not from any magistrate, prince, or potentate in the world, not from any man on earth, or the will of man; but only from Jesus Christ our Mediator, himself being the sole or first receptacle of all power from the Father, Matt. xxviii. 18; John v. 22: and consequently, the very fountain of all power and authority to his Church, Matt. xxviii. 18-20, with John xx. 21, 23; Matt. xvi. 19, and xviii. 18-20; 2 Cor. x. 8. See this formerly cleared, chap. III. and V.
3. Spiritual in the matter of it, and the several parts of this power: therefore called the keys of the kingdom of heaven, not the keys of the kingdoms of earth, Matt. xvi. 19, (as Christ professed his kingdom was not of this world, John xviii. 36; and when one requested of Christ, that by his authority he would speak to his brother to divide the inheritance with him, Christ disclaimed utterly all such worldly, earthly power, saying, “Man, who made me a judge or a divider over you?” Luke xii. 13, 14.) Consider these heavenly spiritual keys in the kinds of them, whether of doctrine or discipline; or in the acts of them, whether of binding or loosing, in all which they are spiritual: e.g. the doctrine which is preached is not human but divine, revealed in the Scriptures by the Spirit of God, and handling most sublime spiritual mysteries of religion, 2 Pet. i.; 2 Tim. iii. 16,17. The seals administered are not worldly seals, confirming and ratifying any carnal privileges, liberties, interests, authority, &c., but spiritual, sealing the righteousness of faith, Rom. iv. 11; the death and blood of Jesus Christ, with all the spiritual virtue and efficacy thereof unto his members, Rom. v. 6; Gal. iii.; 1 Cor. x. 16, 17, and xi. 23, 24, &c. The censures dispensed are not pecuniary, corporal, or capital, by fines, confiscations, imprisonments, whippings, stocking, stigmatizing, or taking away of limb or life, (all such things this government meddles not withal, but leaves them to such as bear the civil sword,) but spiritual, that only concern the soul and conscience;
